|~ Mongo's "final" words.|
Mongo is first seen crushing an ice cream cart under his foot. He then destroys a sign that has a picture of fairy godmother. He quickly gets distracted by a giant Farbucks Coffee cup for display on top of the Farbucks building before he realizes there is nothing in it, so he discards it. Donkey (as a horse) convinces Mongo to follow him to Far Far Away's castle. Mongo and the team begin to storm the castle. Mongo is angered when a catapult's flaming shot hits his upper gumdrop botton, knocking it off of him, to which he kicks the burning gumdrop, destroying the catapult.
When he tries to bring down the bridge, the guards attempt to break him and get rid of him for good by soaking him with hot foamy milk. Mongo is able to resist one soak, but his arms break on the second soak, causing him to fall in the moat. Gingy (who was with Shrek on Mongo's shoulder) jumps down onto him, while Mongo's severed arms keep the bridge open long enough for Shrek to successfully enter the castle. The latter takes out the guards and lowers the bridge as Puss lifts Gingy, who bawls over leaving Mongo.
Mongo is briefly seen in the water, singing during the ending song "Livin' La Vida Loca" by Puss and Donkey.
