When Randolph Turned Rotten

Randolph is a terrific best friend to Ivy-until she is invited to a girls-only sleepover party! Then Randolph's insides change "from very-best-friend insides to horrible, rotten, awful, and icky insides." The newly nasty Randolph tries to burden Ivy with useless party-going supplies: he gives her a tight marshmallow necklace and an uncomfortable flashy hat to wear, and he fills her suitcase with heavy logs. Will the sleepover party be ruined? Full-color illustrations. Library edition with trade jacket added
