Beforehand, to buy a geoduck, you have to go to the bank to deposit enough money. If you don't deposit your money you won't have enough in your account to buy one! They're expensive, after all.

You go to the bank to make the deposit, and there is a kid standing in your way playing with a yo-yo (よ). You try to squeeze past and he hits you in the face with the yo-yo. Now you can't even see, let alone make the deposit.
