That graphics pack is awesome, Rydel - though I should give a heads-up: the next update is going to add a LOT of new content (I did mention that last time, didn't I?). Creatures so far are stu, cataquack, plungelo, coo coo, tulip (opened and closed), wild goombas and yoshis, flifits, sneeds, fire snakes, piranha beans, and crawfuls, and I'm also planning fawfloppers, beehosses, teehee butterflies, power bees, love bubbles, octolots, glurps, clumphs, flying squirrel and cat people (for transformations), and possibly blitties, broggies, and brocks. Probably other things as well. This is largely to deal with the new 'seasonal biome' system, which requires a lot of additional creatures to fill up all the 'blank spaces' left over.
(It's like solving a puzzle that was never intended to be solved! Fun! And yet some things make a strange amount of sense: like the idea that M&LPIT's Toadwood Forest and SMRPG's Forest Maze are the same place in different seasons...tree-stump pipes, infectious mushrooms, and signs of alien life?)
Also, multicolored leather based on creature (and adventure mode reactions to use it). Yes, this includes all yoshi colors as well.
Also, is there anything I need to know in order to ensure that it doesn't mess up the TWBT system? I recall it was rather finicky, unless that's been fixed.
