The server is shaped like a hot dog to go with the theme of Weenie Hut Juniors. It has a handlebar mustache, bushy "eyebrows," red eyes which stick out, two "fingers" on each hand, and a little screen on the front. The robot moves on wheels hidden behind the counter.
Inside of it contains a scanner that proves if a customer is a weenie or not, and it proves that SpongeBob is indeed a weenie.
