Jrrr is a young omicronian, and is the son of Lrrr and Ndnd. He was discovered by Turanga Leela when she looked in a poppler can with one poppler left in and Jrrr opened his eyes and said "mama". Leela then informed everyone not to eat popplers.
Later, when Leela was about to get eaten by Lrrr, he jumped into Leela's mouth, stopping Lrrr and saving Leela.
It seems that, unlike the rest of his kinds, Jrrr is quite friendly towards humans as he managed save Leela and Fry on separate occasions.
- He is one of the few kid characters who actually ages in the show.
