How do you get the Turkey 5th Anniversary Poro Icon?
It was a mission or event reward. Riot's description in the client reads: “Earned by playing a game during the Turkey 5-Year Anniversary event.”
Is the Turkey 5th Anniversary Poro Icon still available?
No. Riot tied the Turkey 5th Anniversary Poro Icon to 2017 (mission reward), and it does not normally bring back past event rewards or bundles.
