A new clip for DreamWorks Animation's Shrek Forever After has landed online.  Billed as the "final" chapter in the series (but there's so much more money to suck from the franchise!), this latest installment has Shrek traveling to an alternate universe after he's swindled by Rumplestiltskin.  In this alternate Far Far Away, Donkey is still chained to a cart, Fiona is fighting for survival alongside her fellow ogres, and as we see in this clip, Puss in Boots has become a fat cat.  Not a greedy Wall Street tycoon, but literally an overweight feline.  The clip spends a minute making jokes at the characters heft and lack of boots.

Hit the jump to check out the clip along with the official synopsis.  Shrek Forever After hits theaters in 3D on May 21st.

Here's the official synopsis for Shrek Forever After:

After challenging an evil dragon, rescuing a beautiful princess and saving your in-laws' kingdom, what's an ogre to do? Well, if you're Shrek, you suddenly wind up a domesticated family man. Instead of scaring villagers away like he used to, a reluctant Shrek now agrees to autograph pitch forks. What's happened to this ogre's roar? Longing for the days when he felt like a "real ogre," Shrek is duped into signing a pact with the smooth-talking dealmaker, Rumpelstiltskin. Shrek suddenly finds himself in a twisted, alternate version of Far Far Away, where ogres are hunted, Rumpelstiltskin is king and Shrek and Fiona have never met. Now, it's up to Shrek to undo all he's done in the hopes of saving his friends, restoring his world and reclaiming his one True Love.
