Goo's not there for anything else but the sword. It's been noted in the past that Goo either has had that sword, or has always wanted it (can't remember).
Goo was coming to take that sword, no matter who has it. So it's just lowkey coincidence.
What is the purpose of having goo finish this fight? I know they want to drag on this fight but instead of this they could have done a tall danny vs crocodile dude.
