Tom and Pradeep go on a camping trip and question Tom's older brother's involvement when paranormal pets go missing. Tom must protect his big fat zombie goldfish Frankie before he ends up among the missing.

Frankie was a completely normal pet goldfish until Tom's evil-scientist big brother Mark tried to murder him with toxic gunk! Luckily Tom and his best friend Pradeep shocked Frankie back to life with a battery, and he's been their zombie-fishy friend ever since. On a trip to the aquarium, something fishy starts going on. Something that almost certainly involves evil older brothers, a vampire kitten, a psychic octopus and a plot to take over the world....

Tom and Frankie, the big fat zombie goldfish, need your help. Decipher the codes, solve the puzzles, avoid the traps, and help thwart Mark and Fang's especially evil plans.
