i know is a joke but the stroll a no magic seal! so no make teleport to Princess Celestia! Spike Can't Teleport by his flame! only those with the seal! no seal = burned stroll! the show a show us spike set only stroll with seal! if is what the fan say like this joke, celestia will tell spike to only use his flame to set stroll but is not! plus i am sure spike need to focus to do it! remenber is like teleportion spell if you dont focus, you will teleport ramdomly!
