Role in series
"No Weenies Allowed"
The only known members are two nerds who have conversations in a stereotypical nerdy fashion and Patrick. Next to the place is a highly developed version called Super Weenie Hut Jr's.
SpongeBob goes here as suggested by Reg for being too wimpy to get into The Salty Spitoon. He goes to Weenie Hut Jr's a second time to heal his cracked fingers in ice cream sundae after a failed attempt at cracking his knuckles.
As the two nerdy fish mention, there are many different days of the week allocated to different events in the place. There are days like Double Weenie Wednesday, which moved to Friday, and Mega Weenie Monday, which moved to Sunday. The only one that remains the same is Monster Weenie Monday.
