Kewpie Dan
From Homestar Runner Wiki
In The House that Gave Sucky Treats, if you gave Strong Bad the marshmallow peep, he put you on his "People I Gotta Egg Today" list. Kewpie Dan was one of the other people on the list.
Clicking on his name brought up a picture of him in a new window with the title "Get Fushling!!" No one is particularly sure what that means. The inset picture appears to show his arm being bitten by a vampire.
