Mario fighting the Green Birdo but has no blocks to throw at her, and shes shooting nothing but fireballs at him. Mario still had that cork that he released to free the Subcons last time. He kept it as a souvenir, so he used it to cork up Birdos mouth as she kept shooting fireballs but was filling up her belly with them because her mouth was corked. Her belly got so big and heavy that she lost balance and fell to the ground as Mario gave her a big ground pound on the belly! Shooting the cork out of her mouth and the rest of the fireballs that are in her. ^^
