Tough Enough - Nick and Sally are trying to guess what animal is the toughest one - is it a lion? Oh no, it must be the enormous elephant! Why not at all, says The Cat. The toughest of all is a teeny tiny Waterbear. Huh? Off to meet Cat's friend Wally the Waterbear. After shrinking down in the Thingamajigger, they find Wally and start to play the Tough Enough game! Wally is tough enough to live anywhere, so it's off to Freeze Your Knees Snowland to test it out. Then they go to the super hot Gritchity-Gratch Desert, then even a trip into space! Wally can live anywhere! He really is the toughest of all! How Cool is Coral - The Cat needs help! He needs to get his fish friend Ting Tang Tony back to his family. Off to Scoobamareen they go! Tony and Cat got distracted while he was drawing pictures of the beautiful coral that's all around them. Using Cat's drawings as a map, they swim to get Tony back home. Along the way they meet little polyps that live in the coral and learn that they actually helped to make it! They learn about how long it takes to make and how delicate it is. Luckily they soon find Tony's family and they're reunited. Back home Nick and Sally make their own coral drawings, cause you never know when the Cat might need help again!
