I didn't know Insaniquarium :O , I just searched that on steam, nice!!, I really appreciate all the feedback :), indeed the rock cannot be picked just going through when it is in front of a bush, it is a bug, and somehow there is a workaround that allows you to pick it if you try to pick it with the Otter's belly, I didn't planned that, just happened. lol. I am really happy hearing it kept you coming back, cheers!
