I have been playing through Beyond Good & Evil for the first time and am very near the end of the game. I am in the last chapter; preparing to go to the moon. However, I do not have enough Pearls to buy the stellar engine and have already connected the Beluga to the hovercraft by installing the Flight Stabilizers. Is it possible to disconnect the Beluga from the hovercraft? It would help me greatly, as I could do several hovercraft focused Pearl challenges. Thanks.

I don't know which version your playing but yes it is possible to disconnect the Beluga from your Hovercraft. When you do that the Beluga will just sort of fly around until you come back for it. 

Yeah, I feel like a dumbass. You hit Square. I started a freaking help thread before I even explored the face buttons. I am a douche.
