SpongeBob's Name Tag is first seen in "Help Wanted." It is used to identify who he is.
SpongeBob's name tag is light blue with a green border, a dark blue anchor, and red letters spelling SpongeBob. The name tag was first featured in the episode "Missing Identity" when SpongeBob loses it and needs to find it before the Krusty Krab uniform inspection , however, it turns out that his pants were on backwards. In "Thank Gosh It's Monday," it looks similar except it has no border around it and it has thick red lines above and below the name.
- The anchor on SpongeBob's name tag is similar to the anchor on the Krusty Krab Employee Hat.
