I do not follow the trends for .mobi, so I cannot really give an appraisal.
It is short, the letters are OK (not sure double letter is an advantage for .mobi) and it means something. The meaning would make it better suited for a child/teenager public. The question is whether that public is likely to hit a .mobi web site.
That could be used as a social web site. I think a "brandable" name would work better for that though.
