[The following Flash game (loud volume warning!) isn't as gross as it could be and was actually fun. It does make some good points and has a fun "bonus" level as well as as useful links (one in particular. links to "Vegan Thanksgiving Recipes" where most can be made no-added fat with minimal effort or impact on taste.
I do wonder, though, how effective these kinds of efforts are. A bit shocking to some viewers, but if even only a handful of people finally get the message on how absurd and cruel the "factory-raising, slaughtering, stuffing, and cooking" turkey process is, maybe PETA's accomplished something useful.]
Note: since the embedded animation loops audio automatically, I've replaced it with a graphic of the lead game frame. You can play the full size version here: PETA.org.
