Abilities & Traits
On the Move
Slippy constantly moves. Even without player input, she will slide in a random direction. Player input still has general priority, with some exceptions.
- If Slippy collides with an obstacle, she will slide in a direction perpendicular to it.
- If the player stops their input, Slippy will keep sliding in her original direction.
- Slippy cannot change direction in 180° directly from the direction she's moving towards, requiring the player to manually make a U-Turn in order to move backwards.
Golden Frog Head
Using Golden Frog Head prevents Slippy from moving, while causing her to body to shake and flash red as she charges up a fart. When the player stops charging up the item, Slippy will unleash the fart, which scales in size and intensity based on how long it has been held.
Other
Slippy has an innate 
The Inner Eye effect, shooting tears in a triple shot similar to 
Keeper's, as well as oval-shaped green tears that are purely cosmetic.
Birthright
"Pungent odor"
Slippy's 
Birthright makes her spawn lingering poison gas clouds when using Golden Frog Head's farts. Her sprite also changes to resemble Golden Frog Head.
