Ice Climber (NES)
Ice Climber is a game about two children named Nana and Popo, who climb mountains.
In the Japanese version, the enemy Topi is a seal. The international releases changed it to a fuzzy yeti-like creature, due to the taboo nature of clubbing seals.
The same change was made in Vs. Ice Climber and its Famicom Disk System port, as well as when the Topi reappeared in non-Japanese versions of Super Smash Bros. Melee. The "8-Bit Hero" microgame of WarioWare: Touched! uses the seal in all releases, possibly because the Ice Climber scene appears so briefly.
In the re-releases on Virtual Console/Nintendo Switch Online, Topi's still appear as seals in Japan and still appear as yeti's in other countries.
