The Tiger Electronics electronic Pokédex toy received major pushback from Nintendo HQ in Japan, which did not want the toy to have any kind of game function as to avoid cannibalizing sales of Pokémon Red & Blue. When two-frame animations of each Pokémon were implemented, they had to be scrapped as Nintendo thought they were "too close to the Game Boy game", despite animated sprites not being introduced until Pokémon Crystal in 2000. Despite this, both Nintendo of America and 4Kids were in favor of the animations.
