Of Mice and Munks is an episode of the ALVINNN!!! and The Chipmunks series.
The Chipettes fall in love with a cute little mouse that's doomed to be fed to a snake as part of a science class.
Simon and Jeanette signed up for an extra credit science class, named the Circle of Life, to the shock of Alvin. The two go to the class and end up leaving with two boxes. Jeanette expresses her displeasure about being paired with Bocarter, and once Simon brings up how Brittany might react to bringing a snake home, Bocarter switches the snake's box with a box for its food. Later, at The Chipettes' Treehouse, Brittany screams at the presence of a mouse but slowly warms up to the mouse Jeanette named Pippi as she explains the situation. Over at the Seville House, Alvin desperately wants to know what's in Simon's box; Simon refuses to tell him, claiming he wouldn't want to know. Simon leaves the room for a few moments and Alvin looks in the box to find a huge tarantula that jumps on his face. Simon returns when he hears screaming, unable to find the spider. Meanwhile The Chipettes dress up Pippi, crying over her being used as food, before choosing to give the mouse the best two days she's ever had. Back at the boys' residence, Simon attempts to locate the spider while Alvin walks on stilts scared. Bocarter continues to call Jeanette, leaving her irritated messages, and decides to feed the hungry snake in class since Jeanette is hoarding the mouse. Since Alvin's terrified of the loose tarantula, he asks Dave to keep a look out while he sleeps. Simon confesses he can't find the spider the next morning, upset he's gonna flunk his report, and the girls explain a plan to save Pippi with a poorly made decoy. At school Bocarter takes the mouse box and locks Simon and Jeanette in a locker to prevent them from ruining his grade. They break out just as Bocarter is screaming about Simon's spider on his face (which crawled into Pippi's box), though Cheesy feeds the snake during the commotion. Jeanette runs out crying before Cheesy explains that he saved her mouse. That night, Alvin's convinced the spider is still in their house, to Simon's annoyance.
