Leapex I believe this to be another of those simplistic pets, where (being a frog) the Leapex is named after physical abilities (namely, leaping). I have, however, found that “Leapex” is an actual word, and so I will give the definition. Leapex: Pilot Lingo for a particularly stupid and useless short-term exercise that for some reason needs to be done now, but can't reasonably be done now, and probably shouldn't be done at all.
