Mikey the Mike Sprite visited the SOL to punish the Bots for their idle wish to never see Mike again. Rather than expressing remorse, Tom and Crow didn't really care about Mike's disappearance, much to the regret of Mikey. Mikey later persuaded Crow to take his wish back, and he brought back Mike. Before vanishing, Mikey warned them to never make a wish like that again.
Shortly thereafter, however, Tom wished that Mike's socks would disappear, prompting a visit from Mikesocksy the Mike's Socks Sprite.
The character was inspired by Coily the Spring Sprite form the short A Case of Spring Fever.
