In respect to dojo tradition, no footwear is permitted in the Battle Arena. As a result, everyone is barefoot throughout the entire match, including Ash and Greta.
Ash's Snorlax uses Rest while it is frozen. This would be impossible in the games, as Pokémon cannot use any moves while frozen.
Normally, Ash says the episode title. In this episode, Ash and his friends all say the title together. This is because they were trying to imitate the opening of the popular game show Wheel of Fortune (1983), which includes the entire crowd saying it.
Ash battles Greta and wins, earning the Guts Symbol.
Ash temporarily adds Snorlax back to his team from Professor Oak's Laboratory for the battle with Greta.
