The hyper obsessed queen of the teeth. One thing is sure, she probably really loves his teeth.

I have a feeling that Tooth and Bunny have a relationship bordering on something like really good friends that borders on a sister-brother relationship, but not the bickering kind, but the soothing kind.

The main problem debating this relationship is, that I can't seem to grasp enough information to define it, because well, there is not much interaction between them, as it is they with other characters, but the fact is that all the guardians are close to each other and they care for each other, feeling like family, because of that, and when at the memorial for Sandman they hold hands, I come to the conclusion that they have a very close brotherly/sisterly relationship.
