Glitch Tutorial: Talking Aquarium

Here's a tutorial on my favorite glitch-one I discovered on my own.

 Next,

 click the "Switch Animals" button.

 After you've gotten to the "Switch Animals"

button, click an animal. While changing, run into the door to the aquarium.

Like this:  

Then you can freak people out.
