Admiral Jelly is a larger, more powerful version of Captain Jelly, encountered in an underwater arena. It will fire homing missiles and deploy electric barriers. The key to this fight is using the Blue Cube Wisp. Admiral Jelly will occasionally expose a vulnerable core on its top. When it does, activate the Blue Cube to quickly sink and perform a powerful ground pound on its head. You'll need to be quick, as it only exposes its core for a short time. Dodge its missiles by swimming around or using quick steps. The electric barriers can be avoided by swimming through gaps. Three hits with the Blue Cube will defeat Admiral Jelly.
