The suffix incidentals are alternate models of regular incidental characters. Instead of their model numbers ending in a single letter such as an "A" or "B" and so on, their numbers end in a whole word in capital letters. The two currently known suffix incidental types are "KID" and "BABY." The "KIDs" make the incidental take the appearance of a child and the "BABYs" make the incidental take the appearance of an infant. There are currently a total of 16 suffix incidentals with there being five "KIDs" and eleven "BABYs."

Role in series[]

The suffix incidentals have made a decent amount of appearances throughout the series. They are meant to have the same functions as regular incidental characters. The "KIDs" have made several appearances throughout the series where they are usually portrayed to be children. They were firstly designed for "Krabby Land." The "BABYs" are more less commonly used than the "KIDs." They have always been portrayed as infants. Incidental 102BABY was the first "BABY" suffix incidental to be introduced in the series, debuting in "SpongeBob Meets the Strangler." In "Goo Goo Gas," all the other ten "BABYs" were introduced where they were portrayed as victims to Plankton's baby gas along with Mr. Krabs, SpongeBob, Patrick, and Squidward.
