Last One in Is a Rotten Egg! by Diane DeGroat features my two favorite opossum siblings, Gilbert and Lola, who are very excited about their cousin Wally visiting. That is until Wally arrives and is so competitive about everything from getting to the lunch table first to finding the most eggs in the Easter egg hunt. Gilbert and Lola work together to find their eggs, while Wally finds as many as he can. When Gilbert and Lola find the prized golden egg, Wally gets it down for them, then keeps it for himself! Will Lola get credit for finding the golden egg? Or will Wally keep it for his own? You'll have to read to find out. I'll give you a hint, the ending is one that you and your kiddies will love.
