While Treelo, Pip and Pop are staying at Etta and Ottos', Tutter holds a sleepover for all classmates at school at the Big Blue House, with Ojo joining in as well. The mice are astounded by the size of the house and everything in it, but Bear does his best to assure them that they'll be well taken care of. He suggests that they think of it as their "home away from home." They decide to play a game called "parmcheesy" and Ojo's worried because it sounds like a game only for mice, but Tutter assures her it wouldn't be a party without her. When it comes time for bed, Keisha wants to call her parents and soon all the other mice do too. As for Tutter, he's a bit worried what the mice will think of his stuffed toy, Kitty, but Bear shows him that they all have their own stuffed toys. As they settle in to sleep, Luke is first uncomfortable with his pillow and then wants to hear a lullaby. Shadow appears to sing her special lullaby, but Luke misses the one sung by his parents and wants to go home.
