@Grivusangel -- You started me thinking about it and I looked for it. Lo and behold, I found it! The dwarf in question went to the good fairy in "Sleeping Beauty" when the princess pricked her finger and fell asleep. It's in the original story by the Brothers Grimm. You can find it in the Andrew Lang collection, "The Blue Fairy Book."
This is the one where the handsome prince's stepmother is an ogress and wants to eat Sleeping Beauty. It's pretty gruesome. But I knew those seven league boots sounded familiar to me, too. I know they turn up in other places. I'll have to check around and see if I find them in other stories.
