When Tom saved Frankie the goldfish from near death (by zapping him with a battery), Frankie somehow became a big fat zombie goldfish with hypnotic powers. Now Frankie is one lethal fish with a mind of his own (good job Frankie has appointed himself as Tom's bodyguard).
When Tom takes Frankie on a trip to the seaside, they meet a strange old lighthouse keeper who warns them about the Evil Eel of Eel Bay - and sure enough, one lightning storm later, Frankie is embroiled in a fishy stand-off with a super zombie eel.
In the second story, all eyes are on Frankie as he takes on a starring role in the school play!
