Water Striders	Level	Location

Water Pincer	65(NPC Level: 5)	The Singing Pools, The Wandering Isle
	In practice this beast is almost impossible to tame: taming exotics requires level 65, and this creature can longer be accessed once your Pandaren leaves the starting zone, so you'd have to level to 65 on the Wandering Isle! Formerly it was much easier to tame, as exotics could be tamed at level 10.
Summit Strider	88	Kun-Lai Summit
