The Ro-Man is catch-able, but I probably should make the catch rate higher.
The squonks are only good for photographs. You can also fish at the lake, and sell fish to the man in the shop. He’ll also pay for photos, and sometimes a little better than the professor.
In all my playtesting and playthroughs, I have not caught the sasquatch. I know, because I re-wrote that section several times, that it is possible to do but I haven’t done it and I don’t know of anyone that has.
But that’s kind of the point. The show upon which the game is based is about one man’s lifelong quest to capture bigfoot, and how that quest shapes his life in other directions. If he catches bigfoot, no more show, you know?
