Adventue Time

A green-skinned, large character in a black outfit stands in a yellow-walled room, emitting streams of white gas from its backside, causing it to laugh and lean forward. A character with brown hair and a white coat enters from the left, looking shocked, as the green character continues to emit the gas. The scene then cuts to two other characters, a boy in a blue shirt and a yellow dog, standing in the same room, looking up with expressions of surprise and amusement.
