I'm not sure where they were going with the "trash cloak" on Burmy, but I think it looks like cotton candy (with straws poking out), to be honest. XD But you have to admire the idea of this Pokemon--it makes you curious to know exactly what it looks like under the cloak it chooses because of its environment. (Yes, yes, we all know "bagworm". But this is the Pokemon world--what does a "bagworm" look like in the Pokemon world???) You can honestly imagine it however you want. :)

Burmy is a straight-up Bug-type Pokemon, with the typical "early stages" limitation on move sets--it also has the potential to evolve differently based on whether it's male or female. Here's some flavor text for you: "To shelter itself from cold, wintry winds, it covers itself with a cloak made of twigs and leaves. If its cloak is broken in battle, it quickly remakes the cloak with materials nearby."
