Inky

Inky is an evil octopus species found in Jolly Roger's Lagoon in the lagoon part of level 4. They will block the tunnels leading one place to another, attempting to whack Banjo with it's many tentacles. They cannot be killed, but can be frozen with an ice egg in the face, or by using the Submarine's sonar attack.

To get past them easily, just speed through using Kazooie's Talon Torpedo.
