What's the point of Poro-snax in aram map

What is the point of the Poro-Snax you get in the map Howling Abyss?

You can consume it when you are close to a "Poro". What will happen? Do you get any buffs or regeneration?

You're actually feeding the nearest Poro when you use it.

There are a few things that happen with Poro-Snax.

• If you have a Poro-Snax in your inventory, Poros will run to you. This is helpful when you see Poros run into a brush as it tells you an enemy champion is in there.
• If you don't have a Poro-Snax, Poros will run away from you.
• When you use a Poro-Snax on a Poro, it increases in size. If a Poro is fed enough, it explodes in a shower of normal-sized Poros.
