This is probably Tyer's most celebrated sequence at Terry: the animation of the cat in "A Cat's Tale" running in terror followed by mice and locking himself inside his cave (a cat living in a cave? And if he's so scared by mice why at the end he tells us that he's not scared by Mighty Mouse, showing his old fraidy side as soon as the super rodent appears tough?).
Oh well, it's Terry.
Enjoy the wackiness!
