Flotzo

Flotzo is a red octopus that replaces Squishy in Kirby's Dream Land's Extra mode. He has a glum expression on his face and two dots (one on top, one on bottom) on each arm. Flotzo attacks just like Squishy but is stronger and faster.

Flotzo didn't appear in any game for a long time but he returned in Kirby Tilt 'n' Tumble, then made a short cameo in the Kirby: Right Back at Ya! episode, "A Fish Called Kine", and eventually returned in the Revenge of the King sub-game in Kirby Super Star Ultra, once again replacing Squishy.

A larger version of Flotzo, featuring a pull-ring on it's back, appears exclusively on stage 6 of Dedede Resort in Kirby Mass Attack. This version of Flotzo has a totally new attack pattern, firing cannonballs at the Kirbys. If the Kirbys pull out the ring on it's back, it will deflate and fly around like a balloon. Also, a regular Flotzo appears in the sub-game Kirby Quest, alongside a Squishy and Sweet Stuff.

Trivia

 * In the Kirby: Right Back At Ya! episode "Kirby Comes to Cappy Town", when the monster named Octacon transforms into his true form, he bears a slight resemblance to a Flotzo in color and appearance.
 * Flotzo bears a similar appearance to the Pokémon Octillery, especially in Kirby Tilt 'n' Tumble.
