Get ready for some more fishy mayhem in this fourth hilarious illustrated chapter book in Mo O'Hara's New York Times bestselling series.

When Tom and his best friend Pradeep rescued Frankie the goldfish from Tom's older brother's evil science experiment by zapping him back to life with a battery, they never expected Tom's pet to become a BIG FAT ZOMBIE GOLDFISH with incredible hypnotic powers...but it's helpful when they are thwarting his big brother's evil plans.

Dodging booby traps, avoiding evil possibly-mummified kittens, discovering the truth behind the ancient Egyptian Curse at the local museum . . . it's all in a night's work for a zombie goldfish!

Then, there's something fishy going on at sports day. Can Frankie help Pradeep and Tom to foil Mark's evil plans? Or will Mark and his pet vampire kitten, Fang, take home the gold?

New York Times-bestselling author Mo O'Hara delivers more laugh-out-loud fun in this illustrated chapter book series.
