Here are two mean and nasty words: Mrs. Cakel

Something has gone wrong in Danny and Calvin's fourth-grade classroom--out of the blue, Mrs. Cakel has transformed from a rampant rule-enforcer to a quiet excuse-accepter. Has she been replaced with an alien? Has she undergone a top-secret personality makeover?

Danny and Calvin decide there's only one way to find out what's really going on--spy. But spying soon leads to a greater mystery filled with dog chasing, jelly-injected donuts, prune butter-included experiments, riddle mania, and more!

Praise for Danny's Doodle's: The Jelly Bean Experiment:

"The first-person narration, realistic characters and occasional line-drawing 'doodles' will keep pages turning."--Kirkus Reviews
