Description
Beatrix wins the Science Fair every year--because she uses magic to cheat! But Olive really wants to win this year, and she has the best science project EVER. Then something bad happens! The sisters' projects turn into a super-stinky, super-moldy blob monster! The blob is ALIVE and growing bigger and smellier by the minute! Can Olive and Beatrix stop the blob before it swallows up the school?
