Power sphere is of ally to fuel egg.

Power-Sphere is a powerful sphere that appears in the secret-room in the game. Power-Sphere has a strong hate for WEDG but a good relationship with the fish.

Power-Sphere has many different colors and can be seen rotating and levitating in the game. Under the sphere are 4 different colored parts which has particles rising from them, these are possibly what gives it power. Power-Sphere could have helped the fish get BadPuffer into the pit.
