Completely agree. Preferred the rays. But apparently it was a sealife decision to add them (part of the "new attraction at every merlin place" thing they've got going on) rather than a towers decision, as shown by pretty much every sealife in the world getting them/more of them this year.

^That... Though I'm not sure how bad the other Spider Crabs have been at killing each other/being shocked about their shedding/being generally crap...
