WMG / Angry Kid

If the shorts had a link between them, Angry Kid would have been Killed Off for Real

In his three-part vlog series, we see that Angry Kid had a familiar-looking firework on his shelf, which happened to be the same one he uses in "Marathon Man". Now, both of the episodes were made in separate times and for different series, one of which being a revival, but there could be a possible link; the vlog series happened before the events of "Marathon Man" because if Angry Kid did use the firework it would not be visible on his shelf. Either that or he just managed to survive from the blast, though severely injured and had another spare one lying around.
