Luna has blossomed up as her job isn't all that high on effort. Her card's info says:
JIOJ-EN000:
My Plump Pony Pal Princess Luna
LIGHT / Plump Pony Pal-Type Xyz / Rank 8 / ATK 0 / DEF 2950
2 Level 8 monsters
Once per turn: You can Tribute 1 "My Plump Pony Pal" monster you control; this card gains 1000 DEF, until the end of the turn. You can detach 1 Xyz Material from this card to target 1 monster on the field whose Level is equal to or less than this card's Rank; destroy that target, and if you do, gain LP equal to that monster's Level x 300.
