Is TM Breeding in the latest version of the game? I'm currently trying to breed sludge bomb on my roselia, and the first step of the chain is to breed sludge bomb on a stunfisk. I bred my male swalot, which knows sludge bomb, with a female stunfisk, but my baby stunfisk doesn't know sludge bomb. I checked on bulbapedia- stunfisk learns sludge bomb as an egg move, and both mons are in the amorphous egg group. So what am I doing wrong/How do I get sludge bomb roselia?
