The Wonder Pets (2006)

S2E8 Save the Platypus!

Ming-Ming suddenly pops up inside Tuck's terrarium, gleefully playing with his belongings, much to Tuck's annoyance. At first, Tuck is simply irritated by her mischief, but things escalate when she purposely reshapes his beloved turtle sculpture into a duck. This leads to a heated argument, prompting Tuck to announce that he’s giving Ming-Ming the silent treatment. Unfazed, Ming-Ming agrees to this tactic with her own frustration. Despite their quarrel, the trio, including Linny, must come together to rescue a platypus stranded in an Australian river and mend their friendship.
