Yarrctopus

"And where do you think you're going? I'll send you to your watery doom!"

- Kamek

Yarrctopus is a mini-boss who appears in Yoshi's Crafted World. He is fought in Yarrctopus Docks at the end of the level, Pirate Pier. As his name suggests, he is an octopus made out of yarn. Due to Yarrctopus only being a mini-boss, defeating him will not recover a Dream Gem.

Once Yoshi makes it to the end of Pirate Pier, Kamek will appear with Baby Bowser, refusing to let Yoshi travel any farther. Using his magic, he repairs a pirate ship in the background and transforms one of its cannons into Yarrctopus, who must be defeated. During his battle, Yarrctopus will remain on the pirate ship, hiding behind three different walls. After a moment, one of the walls will fall over, fully revealing Yarrctopus, who will then attempt to shoot a spike ball at Yoshi. If successful, Yoshi will take damage. If Yoshi is able to hit Yarrctopus with an egg before the wall goes up, however, Yarrctopus will be launched into the sea and return, angrier than before.

As Yarrctopus becomes angrier, he will launch more spike balls at Yoshi each time he appears. Rocks which appear in the water will also obscure Yarrctopus, preventing Yoshi from being able to hit him at certain times. After Yarrctopus is hit with eggs three times, he will once again be launched into the ocean, where he will remain. After his defeat, the level is completed, and Yoshi can advance to Go-Go Land.

Trivia

 * Yarrctopus is quite similar to an Astro-Lanceur, due to both being a version of octopuses and having an attack method of shooting spike balls at a target.
