"Mythical Creatures" translation

Greetings! My ten-year-old son is doing a big school unit on mythical creatures (dragons,  goblins, hydras, cerberus, etc.) and he is hoping to write his title poster in dragon language. Could you suggest a good translation for "Mythical Creatures" ? (He thinks Sunvaar is better than Sivaas... but he can't find anything for "mythical") - All suggestions would be appreciated! Thanks so much!
