the "bumblebee frog" is a leucomela, I don't have any but they are supposed to be awesome - bold, fun, and pretty. a lot of people recommend them as beginner frogs. I have a couple types of tincs (tinctorius species... i have citronellas and azureus) that I love!
I would NOT recommend getting moss out of your woods.... there may be dangerous parasites or microbes in it that will not be good for your frog. chytrid fungus is a big danger as well
pleasedo some reading and searches on this website before you go out and do any more supply-collecting or buying. frogs aren't tough to care for IF you do the proper research and have the time/money/supplies to properly take care of them. but if you don't you could be wasting a lot of money and more importantly - needlessly make your frogs suffer and probably die.
