Keep your endless, pointless debates over nerfed this and broken that- this is possibly the least important rules question ever asked: Should crystal ooze require a DC 20 Perception check to spot them rather than the DC 15 listed in the Bestiary under the Grey Ooze entry (p. 166)? Kinda makes sense they'd be a bit more difficult to notice in water, and it matches the DCs in 3.5 (from the Monster Manual and Tome of Horror Revised).
