Hey Arnold! Gelatin Joust is a short licensed Flash game that was released on Nickelodeon's website in 1999. It's based on the animated series Hey Arnold! and is an adaptation of the episode "Parents' Day", specifically the jousting match between Grandpa and Big Bob Pataki. You play as Grandpa and your objective is to knock Bob off the beam and into the gelatin before he does the same to you.
dekutony in this run succeeds in this rather hard Flash game and beats Bob in record time and faster than in the original cartoon.
