he found bigfoot who was being electricuted and the omnitrix scaned him XD

in all seriousness, shocksqatch was the white yeti guy from the Generator rex/ben 10 crossover special. HOW he was unlocked is that the omnitrix just suddenly made it available to Ben. This happened a few times with various of his aliens including: Cannonbolt (original series FTW XD), Jury Rigg, Ditto, Fasttrack, eatle, Buzzshock, etc.
