Wha --? Oh, it's still on....ah, it wasn't my choice to name it that. Donald and Goofy already named it. Or, maybe it was Chip and Dale since they made it, I think. Anyway, we use the Gummi to get to other Worlds. I wasn't in it or using it at the time I came here though, so I haven't seen it in Asgard. It's made of these Gummi blocks we can use to upgrade it and stuff too. To have better armor or to attack better, or even take us new places.

[Because of that, probably the Warp Gummis might just be Sora's favourite.]
