It's Thanksgiving time and Room Nine is getting ready for their very own Thanksgiving feast! There's even a contest to see which room can write the best thankful list. The winners will get a pumpkin pie! Only it turns out being thankful is harder than it looks. Because Junie B. is not actually thankful for Tattletale May. Or squash. Or scratchy pilgrim costumes. And pumpkin pie makes her vomit, anyway. (But Junie B. is thankful for yummy cranberry sauce that's shaped like a can. And biscuits that explode from their can. And nipsy doodles!) Will Room 9 win the disgusting pie? Can May and Junie B. find common ground? Or will this Thanksgiving feast turn into a Turkey Day Disaster?
