Idk, I could imagine Brachy swimming like a crocodile or Spinsaurus from that 3rd Jurassic Park. It wouldn't matter if the slime was washed off on his way to Ingle Isle, because he went there exclusively to get that stronger slime mold. So perhaps they swim just fine, but have to recover their slime mold upon arrival to wherever they just swam to. It did say there was slime mold everywhere just not activated, right?
