While searching underater for an entrance to the Armada's base, they were attacked by submarines and took enough damage that they needed to surface despite winning, which was serendipitous in allowing Antoine a safe landing from up above. After hiding the Sea Fox, T-Pup led them to a cavern to sneak into the Armada's base from underground, guiding with his lights. Ambushing some Battle Birds with explosives, T-Pup stored most of their bombs while Tails used the rest to blow a faster way to the base, which led to a confrontation with more Battle Birds until help arrived in the form of Bunnie, who took an immediate shine to T-Pup.
