Quaver Gym doubles somewhat as a tutorial area. The antechamber of the gym houses Foster's Center for Children, a school and daycare for the children of Quaver Town and Dacapo Town. The blackboard in the school section contains blackboards showing status effects and type advantages.
Further in is the gym itself, styled as a fort made of bricks of snow and ice. The Gym's trainers are children taught by Foster himself, who hide within snowmen. If the player tries to pass a snowman containing a trainer, they will pop out and initiate a battle.
A slide made of slippery ice descends down from the fort's top level. Trainers that reach Foster can then slide back down to the bottom of the fort.
The gold gym statues found in the Quaver Gym and every Gym afterward are of a pokemon named Goraurum. Goraurum was a proposed member of the Chimpoca line, a huge gorilla plated in gold. This mimics the gym statues in some Pokémon games depicting an early beta version of Rhydon, one of the first Pokémon to be designed.
