Twinkle the Kitten

Twinkle the kitten appeared in the The Goodies episode Kitten Kong, where the Goodies where instructed with Twinkle's care, as instead of growing bigger and stronger, Twinkle was only growing stronger, and at a remarkable rate. Graeme's plan to solve his problem was to feed him his special growth mixture, but the mixture worked too well, as Twinkle became a giant.

The Goodies' response was to prevent Twinkle from escaping, whilst Graeme created an antidote, but Bill accidentally put Twinkle outside at night.

Eventually, The Goodies tracked Twinkle down, and using the Trandem, returned the kitten to normal size.
