In the water based racing game, Hydro Thunder, there is a hovercraft boat called blowfish. This texture is based entirely after that boat. It's nothing special, but it can be carried into other hacks with careful use of BrawlBox.

Here is a reference picture: http://www.habosarcade.com/images/HydroThunder/HydroThunderBlowfish.png

This is retextured using the ORIGINAL STGPIRATES.pac from the BRAWL ISO. So, it should not desync as long as they are using this exact texture pack or the original Brawl STGPIRATES.PAC.

IMPORTANT: In game pictures will be coming soon.

If anybody would be willing to help me make a fuller stage hack, please PM me.
