Skiddo is a quadrupedal, goat-like Pokémon covered with shaggy, dark brown fur. It has a white face with a brown blaze down the middle, a round black nose, black eyes, a short beard, and small rounded ears. On top of its head are a pair of pointed black horns extending out to the sides. It has a white stocking on each leg and cloven, orange hooves. There is a leafy green mane around its neck that extends along its back. The mane ends at its tail, which is made up of three short leaves. Skiddo can perform photosynthesis with the leaves on its back, which means that it does not need to eat so long as it has sunshine and water. It has a docile nature and is thought to be one of the first Pokémon to live alongside humans. As seen in the anime, milk from Skiddo can be used to make dairy products.
Skiddo is based on a goat, possibly a bharal or dwarf bharal due to its horns. It is also based on a bike, as it can be ridden and has riser bar-like horns. The grass that grows upon it may originate from Pan or Faunus, gods of nature who are half-goat, half-human. The grass could also be a reference to the traditional yule goat figures in northern Europe made of hay.
Skiddo may be a combination of skid and kiddo (slang for kid, which is also a term used for young goats). However, the way it is pronounced in the anime implies it may be a corruption of the Ski-Doo brand.
Meecle may be a combination of メー mē (the sound of a goat bleating) and vehicle or bicycle.
