So my fav episode of MLP is when Spike went on a greed rampage, hoarding things/growing into a more mature dragon vastly etc.

Story to this pic in my own idea:

Spike becomes a teen dragon, got inherited his own cave along with much supplies of gems and crystals for food, being in his new future lair gifted to him by Princess Celestia for his birthday. The gems are good, and WON'T make him submit ot greed like the issue he got younger.

Gold and pearls were gifts to him from his pony friends, to decorate his place a bit. Purple Amethyst was given to him by Rarity, in gift from remembrance of him giving her a crystal heart ruby when he was a younger dragon. Of course he eats that one first.
