30

30 is a character in Heavy Is 20, and is visually similar to 20, however, its position in the road sign family is questionable. It is a dark shade of blue with white text and a white outline. 30 does not reveal itself to be possessive like 20, instead it remains on the one Heavy. 30 is most known for saying the title of the animation within the animation, and choosing to revive 20 (with the help of Ol' Geezer Engineer) after Team Captain Soldier attempted a dispossession.

30 appears in the Soldier's Dispenser Collab Announcement, shown in a jail with Yellow-Tongued Spy, Soldier and Sputnik Man, guarded by Eyeless Engineers. 30 hits Sputnik Man and shushes him because of the noise he is making.
