I've had a sceptile that bred with a ditto it knew leaf blade, cut, dig, and rock smash. my friend really wanted one on his coloseum so I bred it, the hatchling had Dig, Cut, Rock Smash, and Leer, I don't know if dig is really a Egg Move....Is it??

It`s a move that Treeco can learn, so when you breed a Sceptile with it, the Treeco will also know it.

Egg moves arent the only moves that can be passed down to hatchlings,tms,hm moves can be passed down to the hatcling also
