This is mostly an inconsistency than a mistery, but I noticed something weird with Wishiwashi's Pokedex entries. Namely, what Moon states about its School Form;
"At their appearance, even Gyarados will flee. When they team up to use Water Gun, its power exceeds that of Hydro Pump."
Except it's not (always) the case.
0+ SpA Wishiwashi Hydro Pump vs. 0 HP / 0 SpD Mew: 48-57 (14 - 16.7%) -- possible 6HKO
0+ SpA Wishiwashi-School Water Gun vs. 0 HP / 0 SpD Mew: 64-76 (18.7 - 22.2%) -- possible 5HKO
252+ SpA Choice Specs Wishiwashi Hydro Pump vs. 0 HP / 0 SpD Mew: 123-145 (36 - 42.5%) -- guaranteed 3HKO
252+ SpA Choice Specs Wishiwashi-School Water Gun vs. 0 HP / 0 SpD Mew: 114-135 (33.4 - 39.5%) -- guaranteed 3HKO
Whoever wrote that entry needs damage calculators.
