Kids in Mrs. Z's class #10

"Series coordinated by Kate Messner."--Title page

"Mrs. Z's class is voting on a small class mascot, since big animals tend to get all the attention. But Thunder hates voting -- it's like sports but less fun. Everyone is nominating tardigrades, while Thunder is hoping for something fuzzy, like a hamster. Then she finds an abandoned baby possum and has a brilliant idea. She'll bring the possum to school and convince the class it should be their mascot! How could they resist picking a real, live animal? But when Thunder'splan goes off the rails, the possum -- and the class--may end up in danger if Thunder can't find a way to fix her mistakes."--From publisher's description
