While searching for Izzy, Sunny finds her relaxing in strange cave within the depths of Bridlewood Forest. But the moment Sunny finds her, the Earth Pony bears witness to resurfacing of a bizarre creature thought long extinct, as well as Izzy's rather... "unique" method of relaxing with it.

And naturally, such an interesting revelation requires a lot of research...
