Choo Choo

Animated cat from 60's cartoon, 'Top Cat'. Choo Choo is Top Cat's right 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."
