Deposit
If you want to buy a geoduck you have to go to the bank beforehand to deposit enough money. If you don't deposit your money you won't have enough in your account to buy even one! They're expensive, after all.
Imagine yourself depositing your money beforehand. Imagine the delicious geoduck you'll be able to buy now that the money has been deposited into your account!

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 see! Now you can't make the deposit!
Imagine trying to make a deposit to your bank after getting hit in the face with a yo-yo. You can hardly see what you're shoving your money into. You hope it isn't the hands of the kid that hit you!
