Safe to say this is a reference to the quest "Whole Lava Love" from monster hunter 4, where guildmarm asks you to find a certain something. to directly quote the quest discription "Those strong arms! That explosive personality! And he's right there in the Volcanic Hollow... Oh, I could faint! Be a dear, Doodle, and give him a wink from me, okay?"
also safe to assume that is Mystery Slime from Brachydios, the monster you find. said slime being highly explosive if not handled correctly. one way or another, she will have an explosive ending.
