Chubby Hamburger Joy Fairy

This is a super greedy / gluttonous joy fairy that was born over 300+ years ago. They were born when someone cried tears of joy from eating the most delicious hamburger in their life, and ever since then, this joy fairy has been crazy for hamburgers. They ate so much that they are chubbier and bigger sized than normal joy fairies, who are usually pinky-sized. Their height is about that of a McDonald's Cheese Burger. They have on a hamburger costume, a real one that they can nibble on as they go about their day. When it gets almost finished, they have to find another one. I don't know how they manage to make it into a costume that they can wear, but somehow they manage to. They have self-renewing clothes underneath that repels the sauce and oil and anything else from the hamburger costume. Anything else that gets on their bare skin is eaten away. They want to find a keeper because they suddenly felt guilty for "stealing" away hamburgers in public, and want someone that will cherish them, along with also loving hamburgers together. They impart the joy of eating, especially when their keeper is eating hamburger. With them, you may smell hamburger smells in your vicinity. The smell may also cause you to become hungry, reminding you to eat, if you are someone that forgets to. Even if the smell doesn't, they will be vocal about telling you to eat, because eating is joy.
 
Note: Having this one as a companion is a little special, because they will tell you when their hamburger is running out, and you need to buy a new one to offer it to them, otherwise they get very sad. Please don't forget to buy them and offer a new hamburger to them, otherwise you're going to make them commit a "crime" to go into the public to get their hamburger. After you offer it to them, you absolutely cannot throw away the hamburger in their presence because that would be blasphemy.
