Biography
Sometime between the events of the second film and the third film, Meatlug has offspring again. It is uncertain how many she has, but Fishmeat is the only one that Fishlegs continually carries around in a pocket on the front of his fight suit. He even brings the baby along on a dragon rescue mission, the footage of which was seen at Annecy Film Festival, June 14, 2018. Hiccup annoyingly asks Fishlegs about "the baby" being present during the raid, to which Fishlegs responds he was unable to find a babysitter.

Physical Appearance
Fishmeat is a small, roly poly baby Gronckle, with brownish rough skin on its upper body, and a softer yet bumpyier yellowish underbelly, with yellow eyes.
