drag it to your bar and SPAM!!!!
the faster you spam, the more pets!
You don't see them all, but everyone else will.
If you get 2 friends doing this with you, you can drop the frame rate in Org or IF.

Doesn't work.
/script UseContainerItem has been restricted to Blizzard signed UI mods.

A macro script has been blocked from an UI action only available to the Blizzard Ui.
