Iggy Loomis and his cool superpowers are back in this illustrated sci-fi chapter book for elementary school fans of The Adventures of Captain Underpants

Daniel is trying really hard to be a good older brother, especially now that Iggy has mutant insect abilities that he got from the alien next door. But when Iggy flushes the alien's pet hagfish down the toilet, he goes way too far. Now Shirley the hagfish is fated to a life in the sewers! It's up to Iggy to use his powers to find Shirley, but with his temper tantrums and fits—and everyone on Daniel's case—it looks more and more like Shirley will never come home. Can Daniel convince Iggy to save the day, before everyone is grounded for life?

With aliens, superpowers, slime mold, pets, extra-slimy creatures, and Jennifer Allison’s laugh-out-loud humor, this sequel to Iggy Loomis, Superkid in Training
is an out-of-control good time!
