What's wrong with crabs? EDIT: also, there were loads of puzzles on the notice board, in the last dev diary JaGex said that most of the puzzles had been solved, including the Chaosudoku and the calendar. I haven't had time to analyse them in great detail, if you could post a few more results it would be nice, and also if a mod could merge together a thread with the answers in, and get a better response, because i've only seen a few dotted around different threads.
