From the Super Mario Wiki
A Squiglet is an enemy in the game Super Paper Mario. It attacks by running into the player. It has 2 HP and its attack is 1. It has at least four black legs. Their card is found on top of Bestovius' house. It is number 044.
Squiglets fill the role of Goombas in the game, as they simply walk back and forth, and can only damage Mario if he comes in contact with one of the creature's sides. However, the difference between the two is that when a Squiglet spots Mario, a Squiglet will hop up and down instantly, a behaviour it seems to outgrow in its other forms. Like red-shelled Koopa Troopas and Blue Shy Guys, they do not walk off ledges. Squiglets are more common then the Goombas. They very often come in pairs which is what is called a Squiglet Army, Squiglets with their leaders the Squigs.
They appear in the Flipside Pit of 100 Trials in rooms 1, 3, 8, and 97.
