Patnaik welcomed Olly with a flower bouquet at the state secretariat. He had earlier flagged off the roadshow on June 12.
Olly belongs to the endangered Olive Ridley sea turtles that travel thousands of miles in the ocean and arrive in millions every year on the Rushikulya and Gahirmatha beaches of the state for their annual nesting.
The mascot toured all the district headquarters of Odisha to generate awareness amongst the people of the state.
The four-day championship will begin on July 6 at Kalinga Stadium in Bhubaneswar.
