This buddy is SpongeBob's special friend, which you can see in a SpongeBob SquarePants episode from season 2 titled Bubble Buddy. In this episode, SpongeBob creates a sentient soap bubble named Bubble Buddy out of loneliness. However, trouble ensues when the seemingly lifeless bubble causes chaos at the Krusty Krab and Goo Lagoon. Eventually, it is revealed that Bubble Buddy is conscious and alive. In our fanart SpongeBob Bubble Buddy Work Sticker, we see him diligently go to his job like any hardworking individual.
