okay, so only one red float should exist in play area.
so for example, if i chose water deck instead of my hand and I drew one with float symbol and im not close to capturing my fish yet, then i play that card as usual covering my recent played card but then i have to cover the float this next turn with water cards in my hand or in water deck. this one i think i get it now
the second paraphrase of the float movement is still not making sense in my small brain sorry
but at least i get the idea of the "only one float symbol on play area" and understand the setup correctly. now i am motivated to print them later tonight and play them!!
