#22 - The Wolfrat
Season 1 - Episode 28 - Aired 10/30/1985
MUMM-RA has a phial of miniaturization gas. VULTUREMAN builds a mechanical WOLFRAT to infiltrate the gas into the Cats' Lair. The THUNDERCATS are immediately reduced to nine inches high. Knowing how vulnerable the THUNDERCATS are in this state, MUMM-RA orchestrates a MUTANT attack on the Cats' Lair. The THUNDERCATS' only hope is SNARF; they armor SNARF and use him as a battle charger while TYGRA works on an antidote. The THUNDERCATS finally take the antidote, and SNARF, getting an accidental whiff of it, grows to huge proportions. In his gigantic state, SNARF terrifies the MUTANTS and puts them to flight. Moral: Sometimes in our minds we may overemphasize the importance of certain physical characteristics. We may feel bad or worry that we are at a disadvantage if we don't possess a quality. For some, physical size and strength is a desirable trait. But often it is given too much importance. In reality, the lack of a physical quality does not have to be a deficit and it may be counterbalanced by other characteristics. In this episode, the ThunderCats find themselves physically mismatched in fighting the Wolfrat, when they are cut down in size. However, they use speed, improvisation, teamwork, and determination to persevere against the robot and the Mutants. The lesson for us is that we must never place too much importance on any one characteristic, but should strive to grow in and use all of our personal qualities. It is our whole personality that counts, not any one trait.
