The Temple of the Fishes is a temple found deep in Atlantis under Jolly Roger's Lagoon in Banjo-Tooie. It is initally closed, but can be opened by firing eggs into the baskets held by the mermaid statues in front of the building in a specific order. Each basket is marked by a Greek letter: Σ, Δ, Π and Ω, and the pattern in which they must recieve an egg is as follows: Ω, Π, Δ, Σ, Ω, Π.
Inside the Temple of the Fishes, Chris P. Bacon can be found attempting to take pictures of the ancient paintings, and needs help getting protected from the piranhas.
