As graduation day approaches, Isabel tries to convince her teacher that she and Walter, both porcupines, should receive balloons on the big day just like the other children.
Enjoying gift bookmarks but tiring of receiving them for every single special occasion, porcupines Isabel and Walter look longingly at the bright balloons that all of the other animals receive and fear their sharp quills will prevent them from having as much fun. 40,000 first printing.
Balloons are bright and floaty and shiny and perfect.
More than anything else in the whole wide world, Isabel wants a balloon. Everyone will get one on Graduation Dayeveryone except the porcupines, because Porcupines + Balloons = Trouble
But Isabel isn't going to settle for another boring bookmark. She has a plan. . . .
