No one has ever seen a nurgling with a pogo stick before. This little roly ball of plague joined the team after a particularly vicious hit by Vuzgroth, demolishing goblin, pogo and all.
Now in his re-life the team's newest addition has found that he just isn't agile enough to go hopping about the field anymore, but still carries the stick with him as a memento.
Accusations that he occasionally uses it as a weapon are entirely unfounded of course.
