It looks like a Wiggler except it has about 18 segments and 6 arms, it has drilling teeths in it's mouth and ant-like teeth from it's mouth resembling a insect in real life, and is a giant. Like the one from Super Mario Sunshine, it is colored dark green and it has 5 flowers instead of one and is a dead flower. And it's shoes are colored dark teal.
It behaves like any Wigglers (walking in places), except it can easily trigger it's anger when easily laughed, teased and etcs, instead of losing it's flower, it has a strange way of drilling by using it's teeth, and can breath in space
It makes it's debut in this game, it appears in a chapter called Dreaming in a Nightmare, it was seen attacking several people in Stony Tunnel. It attacks by shooting acid balls at him, running into him, bashing into him and biting his leg, if it is hurt 10 times, it will trigger it's 2nd phase (angry form) and start speeding up any attacks it makes, if harmed 5 times, it will be defeated, making the Stony Tunnel safe to explore
- It is unknown how it exactly became mutated.
