Titre original : Operation: F.I.S.H.Y.
Numbuh 4 shakes the bowl that contains Numbuh 3's pet fish, Mr. Fishy, and kills him by accident. When Numbuh 3 sees her fish dead, she assumes he's just sleeping. The team decides that Numbuhs 2 and 4 should dump the fish while 1 and 5 try to win a new one from a fair, all without Numbuh 3's knowledge of the plan. After they leave, Numbuh 3 comes to check on Mr. Fishy and thinks that someone stole him when she finds him missing.
