There Were Poros. In Summoner's Rift.

If this is indeed unintentional, don't fix it please, but...

An hour ago, I had played a 1v1 with a Jayce as Sejuani, and inside my base, and only mine, was one poro with decent graphics that I couldn't interact with. Another was sitting on the right-hand ledge. Throughout the game, they didn't move, reminiscent of the non-roaming poros in Howling Abyss. I know the majority of you won't believe me, or might have an extremely simple explanation, but this was a nice surprise.

I was unable to capture a screenshot, and I have next to no proof that this happened, considering the enemy Jayce didn't go into my base and see it. However, if anyone else knows about this, please share.
