What is it with fish and this game series? Seriously?
There is a pelican in the trash bin.
Drive it away with something bad tasting.
Use the salt shaker (you get it from the restaurant behind the reception) in the trash bin.
Now it has its beak open and that juicy fish is jumping there. Go grab it.
Maybe you should use some tool to keep its beak open for a while.
Get Bozo's clothes from the laundry and take the coathanger. Use the coathanger on the pelican. You have a fish now!
