Eggs is a member of the notorious gang The Felt whose specialty lies in travelling backwards in time thanks to the timer device embedded in his skull. His general incompetence with time travel causes several paradoxical copies of him to appear whenever he starts abusing his power. Combined with the horde of yolky clones bursting out of his back and the unstable nature of time in certain parts of Tick-Tock Town, circumstances quickly grow out of hand. The other members of the Felt use Eggs primarily as a one-man brute force squad, capable of handling huge amounts of guards or crowds at once, and only ever needing one other Felt to stick behind and clean up the copies.

Eggs comes from a purple-striped moon orbiting a particular planet near Tick-Tock Town. He came to join the Felt after the paradox-generating nature of his powers made his fellow leprechauns force him into permanent exile. Within the Felt, Eggs tends to keep to himself, and the only Felt he hangs around regularly is Biscuits and occasionally the equally quiet Matchsticks. Of the Biscuits/Eggs duo, Eggs is ironically the more level-headed one. While he may not be that smart, he does try and think things through calmly, compared to Biscuits who prefers to sometimes literally charge straight through problems. Eggs tries to keep a handle on him whenever possible, although even he admits that watching passers-by tumble and toss through the air after Biscuits charges past is hilarious.

The yolk clones that burst out of Eggs’ back rarely live longer than an hour after they separate from him, completely dissolving into a foul-smelling paste shortly afterwards. Eggs has gotten used to seeing them go, but he’s always a little downhearted to see them melt away. His personal favorite spots in the city are the natural parks that spot the Felt territory. He can spend whole hours wiling away time, watching assorted animals or just generally meandering about. He absolutely loves greenery, but despite this will adamantly refuse to set foot on any of Tick-Tock Town’s satellites or even leave the city unless absolutely necessary. He has an intense phobia thanks to events that transpired during his exile from his home moon, a phobia which has also left him with a disdain for authority figures. He agreed to join the Felt primarily so he could ultimately get back at the leprechauns that threw him out, the thoughts of which are one of the few things that can break his usually calm demeanor.

He also enjoys finely made sandwiches and desserts, and likes to try out cooking every so often.
