If it has sunshine and water, it doesn’t need to eat, because it can generate energy from the leaves on its back.
– Pokémon Y Pokédex
Skiddo is one of my fave gen 6 Pokemon, it’s so cute! I love the sleeping Skiddo in Lumiose and I want a plushie of it.
Its Pokedex entry seems to imply that it can get its nutrients by photosynthesis like a plant, which explains its ability being Sap Sipper, which makes it immune to Grass type moves and increases Attack by one stage when hit by a Grass move.
In XY, you can ride Skiddo for a small segment, and they go really fast. It feels like a prototype of the Ride Pokemon in SunMoon.
