Animated cat from 60's cartoon, 'Top Cat'. Choo Choo is Top Cat'sright hand man. Definitely the cutest cat of the gang. Never seen without his tight white shirt.
Top Cat: "Hey Choo Choo, do you ever take off that tight white shirt of yours?"
Choo Choo: "Nope. Eating breakfast = tight white shirt. Playing tennis = tight white shirt. Sleeping = tight white shirt. Having sex = tight white shirt."
