Huggy-wuggies!!Kissy-kissy~!!Heeheeheeheehee!!"De arimasu" (であります）is a Japanese phrase used to denote how something is, akin to "desu" (です). Black-Tailed Prairie Dog ends most of her sentences with it, so she is associated with the phrase, and in this context it doesn't seem to denote anything in particular. Additionally, "wwwww" is Japanese Internet slang used similarly to "lol".
