Born from the collective determination of countless recreational players who spent the summer of '87 feeding quarters into arcade machines and practicing disc golf throws until their fingers bled, this entity emerged from the practice baskets behind Sunset Lanes Arcade. Legend says it first appeared to a struggling amateur who was about to quit after missing his hundredth consecutive putt, whispering 'insert coin to continue' until the player achieved his first ace.

Standing barely three feet tall with luminescent green skin that pulses with neon circuit patterns, the Grind Goblin's oversized hands are permanently stained with chalk dust and grip tape residue. Its eyes glow like arcade cabinet screens, displaying scrolling high scores and personal bests of every player it has ever encouraged. The creature's pockets jingle with an endless supply of quarters that never run out, and its breath smells faintly of pizza and determination.

Appears during the most frustrating practice sessions and tournament struggles to transform giving up into grinding harder. It feeds on the energy of repeated attempts and grows stronger with each failed throw that leads to eventual improvement.
