I am SO PSYCHED about the 4x buddy candy! I've buddied up with my Snorlax and I'm going to walk my legs off. Snax needs powering up, and I haven't hatched or caught a new one in longer than I can remember.

Fingers crossed that "rock types" includes Larvitars. Those are at least not hopelessly rare as 10K egg hatches, but still... those candies accumulate awfully slowly, and more would be brilliant.
