His pristine garden was ruined when the Doom Seed began to sprout weeds throughout the city, with the first appearing in the middle of Grumpy's lawn. Sonic the Hedgehog arrived to help but angered Grumpy when he ran over his strawberry patch. When more weeds appeared, Sonic locked Grumpy in his own shed to avoid the danger. Sonic disappeared to tackle more weed sprouts, but returned with Amy Rose and Tekno the Canary to investigate the source. Still stuck in his shed, Grumpy ordered the hedgehogs to leave his garden. After being freed from the shed, he then yelled at Tekno for using a Drilling Machine on his lawn.
