Feed the Poros on Howling Abyss- Eater Egg

Poros are little fluffy, sheep-like creatures that inhabit the Howling Abyss. 
They are harmless and pretty shy. If you approach them, they'll try to run away from you. Unless you're holding some Poro-Snax. Poro-Snax can be obtained iby putting one point in the Biscuiteer mastery. it'll take up one item slot until consumed. 
Poros will happily follow anyone holding Poro-Snax. Activate it like a health potion to feed a nearby Poro and make it grow. Multiple players can feed the same Poro to make it grow even larger. If all ten players feed the same Poro with Poro-Snax, it will explode into seven little Poros, scattering from the center.
