On easy mode, walls do not damage the player. Additionally, on the game's normal difficulty, touching a wall will cause damage to the player. The player is given a harpoon gun to attack enemies by pressing A however, they will not be able to attack on the climb back to the top of the level. Physically touching any of the sea creatures will result in loss of oxygen, as well as either the attack power up or a Treasure Trove, with the attack power up taking precedence if collected. The objective of Tiger! Tiger! is to collect Ether Crystals and Treasure Troves while slipping by enemies, as the character descends to the bottom of the level and returns to the top. There are 5 stages of the game, and each stage is unlocked automatically after some story progression. Whilst the former can be used to upgrade Poppi through Poppiswap directly, the latter can be used for things like increasing slots or creating more mods.

The other reward from playing the game comes from "Mods" and from "Ether". The end score that is achieved at the end of a Tiger! Tiger! game is relevant for improving Poppi's affinity skills.
