A Mario Kart-inspired side-scroller beneath Laborratory, hosted by the lizardman King Carlo.
Carlo Cart is the Mario Kart bonus stage. Per the wiki trivia, the stage is based on the kart racing genre and Nintendo's Mario Kart series specifically. The "Can't stop moving" effect locks the player into perpetual right-scroll, and two stage-specific pickups (Accelerator and Checkpoint) replace the usual stage-item drops.
The setting is the Laborratory underground. According to the wiki description, Carlo Cart is built in the old King Bible underground train station tunnels beneath Laborratory, now repurposed for chaotic go-kart races run by the lizardman King Carlo. The King Bible reference also doubles as a Rome Metro callout to the Rebibbia underground station.
The unlock target is precise. The wiki specifies 25,120 total damage dealt by the trains in Laborratory across any number of runs. Hyper unlocks by default the moment Carlo Cart opens. The shortcut is the thenextstopis spell from the Forbidden Scrolls of Morbane.
This guide covers the 15:00 compressed timer, the train-damage 25,120 unlock target, the thenextstopis spell shortcut, the Accelerator and Checkpoint pickup mechanics, the Roast Chicken disable quirk, the looping-tileset map trick visible with Je-Ne-Viv, and the Mario Kart and Rebibbia station references.
Carlo Cart, the fifth bonus stage. Patch 1.10, released 30 April 2024.
Accelerator (35% speed for 5s) and Checkpoint (+5% Growth, Luck, Greed, Curse, Move Speed, Magnet per pass).Two unlock paths exist. The canonical route is dealing 25,120 total damage with the trains found in Laborratory. The shortcut is the thenextstopis spell, cast inside the Forbidden Scrolls of Morbane that drops from the Bone Zone.
| Route | Steps |
|---|---|
| Train damage in Laborratory | Per the wiki, 25,120 total damage with the Laborratory trains (Take Us Away map event) across any number of runs. The counter persists between attempts |
| thenextstopis spell | According to the wiki, casting thenextstopis in the Forbidden Scrolls of Morbane unlocks Carlo Cart immediately. The Forbidden Scrolls itself drops from the Bone Zone challenge stage |
| Hyper unlock | Hyper mode unlocks by default the moment the base stage opens. No separate boss kill required |
The 25,120 train-damage target is precise enough that most players hit it accidentally over 3-4 Laborratory runs that already use the Take Us Away train as a clear tool. According to the wiki, damage from the trains specifically counts, not the player's own weapons. Position the character to ride alongside the trains for efficient counter progress.
Carlo Cart runs a 15:00 timer, shorter than the 20:00 challenge stages and the 30:00 standard stages. Per the wiki, the stage effect "Can't stop moving" locks the player into perpetual right-scroll, similar to Hectic Highway. The destructible chance is unusually high at 20% baseline (max 60% with Luck).
| Stat | Normal | Hyper |
|---|---|---|
| Time limit | 15:00 | 15:00 |
| Player move speed | x1.25 | x1.5 |
| Enemy move speed | x1.25 | x1.5 |
| Projectile speed | x1 | x1.1 |
| Gold multiplier | x1.2 | x1.7 (+70%) |
| Luck bonus | x1 | x1.1 |
| Starting spawns | 20 | 40 |
| Destructible chance | 20% (max 60% w/ Luck) | 20% |
| Max destructibles | 12 | 12 |
| Effect | Can't stop moving | Can't stop moving |
| Theme | Catch you at Carlo's | Catch you at Carlo's |
The wiki notes the "Can't stop moving" effect mirrors Hectic Highway's right-scroll mechanic. Player movement leftward is futile because the scroll counteracts player motion, so combat positioning happens on the vertical axis. In our testing, 
Wings is the wasted-slot passive here because the stage forces forward motion regardless of Move Speed stack.
Carlo Cart replaces standard stage items with two race-themed pickups that spawn on the tracks. Per the wiki, the Accelerator and Checkpoint are exclusive to this stage and drive the pickup-economy on the run.
| Pickup | Effect |
|---|---|
| Accelerator | Per the wiki, touching it accelerates stage scrolling AND player movement by 35% for 5 seconds, without affecting the clock speed. Use it to flee large groups or rush east toward pickups |
 Checkpoint | The wiki specifies the Checkpoint spans the entire vertical track and cannot be missed. Touching it moves all left-behind treasure chests and pickups to the right side of the stage, plus +5% Growth, Luck, Greed, Curse, Move Speed, and Magnet per checkpoint passed |
According to the wiki, the Checkpoint stat bonus stacks across every Checkpoint passed in the run. A standard 15-minute Carlo Cart clear hits 4-6 Checkpoints, which scales the per-pass +5% into +20-30% across six stats simultaneously. The buff is permanent for the run duration.
Treat Checkpoints as the primary build mechanic, not an afterthought. Per the wiki, the +5% across Growth + Luck + Greed + Curse + Move Speed + Magnet means each pass equals roughly half a Crown plus half a Stone Mask plus half a Skull O'Maniac in stacked stat value. In real runs, the fourth Checkpoint pass is when the build feels like it transitioned from a kart stage into a stat-overload victory lap.
The Roast Chicken with a Clock in the Middle pickup is disabled on Carlo Cart. Per the wiki, the disable applies regardless of whether the player sealed the pickup in their Collection. This removes the standard 50-HP-and-Clock emergency-revive button from the build.
| Pickup | Carlo Cart status |
|---|---|
 Roast Chicken with a Clock in the Middle | Disabled per the wiki. Does not spawn on this stage even when unsealed in the player's Collection |
| Standard chicken (HP only) | Normal spawn behavior. The HP-only chicken still drops from light sources for HP regen |
Build implications matter here. According to the wiki, the disable means runs that depend on the clock-reset for survival (common on tank-stat-low Curse-stacking builds) lose their safety net on Carlo Cart. Plan for sustained survivability with 
Pummarola or recovery-stacking characters instead of relying on Clock emergencies.
Carlo Cart is layered with multiple references. Per the wiki trivia, the stage is based on the kart racing game genre and Mario Kart specifically. The description threads in a King Bible reference that doubles as a Rome Metro callout to the Rebibbia underground station.
| Reference | Source |
|---|---|
| Stage concept | Per the wiki, Mario Kart specifically. The right-scroll track, Accelerator pickup, and Checkpoint mechanic all map to classic kart racing tropes |
 King Bible underground station | The description references the in-game King Bible weapon and, indirectly, the Rebibbia Rome Metro station per the wiki trivia |
| Carlo (lizardman) | The lizardman who hosts the races. The "Catch you at Carlo's" theme name leans into the casual go-kart-club framing |
 Looping tileset | According to the wiki, the stage actually re-uses two tilesets that loop over the entire map. Visible only with Je-Ne-Viv, whose ability to "eat" map objects causes destroyed parts to re-appear on a regular basis |
| Laborratory map source | Per the wiki, the looped tileset is specifically the bottom area of the Laborratory map. The connection ties the train-damage unlock requirement to the literal stage geometry |
The looping-tileset detail is the deepest cut. Most players never notice because Je-Ne-Viv is the only character whose ability exposes it. According to the wiki, every Carlo Cart run is technically the same short loop of two tile patterns played on repeat, which makes the 15:00 timer artificially long for the amount of actual unique map content.
Pair Carlo Cart runs with the Pummarola recovery stack that replaces the disabled Roast Chicken and the Gold-gain passives that pair with the +20% stage Gold multiplier.
