The Wonder Pets - Season 2 Episode 8 Save the Platypus!

When Ming-Ming appears out of nowhere inside Tuck's terrarium, she playfully messes with his things for her own amusement, to Tuck's dismay. Initially, Tuck is frustrated with Ming-Ming's antics, until it is the last straw when she deliberately rearranges his turtle sculpture into the shape of a duck, leading to an argument between the two. Tuck angrily declares that he is giving Ming-Ming the silent treatment, and unimpressed with this gesture, Ming-Ming angrily agrees. Nevertheless, the two plus Linny (who tries her best to dissolve the duo's argument) must still have the chance work together to help a platypus stuck on a river in Australia and restore their friendship.
