Capture the poro
Map: Poro map of course.
Map changes: No towers.
Gameplay: a poro appears in the middle of the map, your team has to use poro snax (on a cooldown instead of one use) to lure it back to the nexus. Once used, it will follow you. If the other team gets close, they can give the poro a snack and steal it (or kill you first). Getting a poro to your nexus gives your team 300 GP and another one spawns in 30 seconds.
Goal: team with the most Poros in 20 minutes win.
