Inkopolis Tower is a large, green tower that sits in the middle of Inkopolis. At the base of the tower,players can access online multiplayer modes such as Regular Battle and Ranked Battle. Jellyfish citizens can be seen waving and dancing from the top of the tower. However, the top of tower is inaccessible to players.
If Hero Mode is beaten, the Great Zapfish will appear on Inkopolis Tower, wrapping itself around the middle of it. It does not affect gameplay, only the appearance of the Tower from then on.
Inkopolis Tower is the counterpart of Tokyo Tower in Tokyo.
