Kem is Wrong Spoink evolves into Grumpig. (I know from personal experience) at the time of the low or high tide time (check every so often every six hours or so it changes be patient). It is just VERY rare at the icy part of shoal cave capture an Male and Female so you dont need to capture more. (You can breed them at the DAY CARE HOUSE.) Also it should start to evolve to Glailie at level 42.
