Thank you! And yes the core game is very much a grab-bag of TFs. You have land animals, birds, some sea life, a few mystical beings, some bugs. This one is all aquatic/semi-aquatic animals do to the theme and the story.
And ya its not to hard to mix and match, the story of this one doesn't work perfectly with the story of the base game, but you can easily swamp characters in and out or tell the base games story with this case and these TFs or this games story with the base games cast and TFs. Really anyway you want to cut it, you might just need to make a few new 'secrets' or alter bios to fit.
