In the Kickstarter-exclusive Outdoor Expansion for Aqua Garden, the player now has an additional tank, the Outdoor aquarium.

Each player will receive a unique meeple - either a whale, an orca, a dolphin or a sea lion - each having a unique ability, as well as a special outdoor tank. Once per round, the player has the option of placing a creature in the outdoor aquarium instead of the indoor ones, to either gain 2 funds or activate special abilities.

The Outdoor Expansion also adds a new type of advanced pieces: the Jellyfish, which counts as a joker fish piece to complete milestones.
