Let's Play Pokemon Yellow (Walkthrough) - #22 Coin Case and Game Corner
I return to Celadon after a few trainer battles and explore the "Rocket" Game Corner as well as obtain a Coin Case needed to play the slots.
Not really much progress here since all I do is fail at the slot's timing, but I do win one time. Next time, I'll talk to the Rocket standing in front of the poster inside the building. Until then...
