King of the beasts: Heathcliff and Iggy go to visit the zoo so that Heathcliff can finally meet the king of the beasts: the lion. But to Heathcliff's dismay, the lion is a kindhearted and gentle creature and not at all to Heathcliff's liking. The apes in the zoo make fun of the lion because he is so tame. Heathcliff gives the cowardly lion some pointers on being fierce and strong which helps the lion put those nasty apes in their place!

Smoke gets in my eyes: The Nutmegs tour the fire station and are very embarrassed by Heathcliff's behavior. That night, while sleepwalking, Grandpa Nutmeg sets the house on fire and Heathcliff saves everyone by getting the firemen there in time, thus redeeming himself for the way he'd acted earlier.

City slicker cat: J.B. is a rich, snobbish cat who comes to visit the Nutmegs. He expects Heathcliff to wait on him paw and paw, and even vies for Sonja's attention. However, Heathcliff discovers the dark secret of J.B.'s past and uses the information to his advantage.

Spike's cousin: Spike's cousin, Bull, is a ferocious looking guard dog who sports a bone out of his mouth the way a tough guy might use a cigar. He convinces Spike that he no longer should take guff from Heathcliff and proceeds to teach him to defend himself but to no avail. After Bull has harassed everyone in the neighborhood, he challenges Heathcliff to a fight in the vacant lot on Elm Street and guess who wins? Who else, Heathcliff!

Heathcliff's pet: Heathcliff hears Iggy saying how wonderful it is to have a pet, and decides he should have a pet too. He tries out Spike and Mungo, but they do not make good pets at all. He frees a live lobster from the fish store which makes a great pet until the lobster begs to go home to the ocean and Heathcliff generously complies.
