When Tom rescued Frankie the goldfish from his older brother's evil science experiment by zapping him back to life with a battery, he never expected his 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.

Tom and Pradeep are about to find out the truth behind the ancient Egyptian Curse of the Cat King, when their evil big brothers crash their overnight stay at the history museum. Dodging booby traps, avoiding evil, possibly mummified kittens...it's all in a night's work for a zombie goldfish

Then, there's something fishy going on at sports day. All the athletic kids seem to be losing their sporting abilities, while Tom's evil big brother Mark has suddenly become amazing at every single sport. 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?
