Trying to breed Relaxaurus Lux

[Guts]

As the title says. I have a male Relaxaurus and a female jotlhog. They keep giving me a Kitsune, which doesn't really make any sense. Am I doing it wrong, or is the fusion just rare? I know I can just go to the dungeon to get one, but I wanted to test breeding.

Also, does relaxaurus always have glutton? Is there a way to get that trait with breeding?
