Ogres

Ogres generally resemble humans with taller and bulkier bodies that give them greater strength than most humans. However, ogres are rather limited in their intelligence, which is usually displayed in how they act and speak. Bigmouth is the ogre that the Smurfs constantly run into from time to time in the forest where they live. There is also a frozen ogre that was guarding food that he stole from the Smurfs in the episode "Spelunking Smurfs" who was frozen along with the food by an enchanted diamond that curses its selfish owners with being frozen. When the Smurfs thawed out the food, the ogre was also thawed out and attempted to stop the Smurfs from taking the food, but Papa Smurf reminded the ogre about the last time he was selfish, and so the ogre decided to share the food and gave the diamond to the Smurfs, saying that it gave him the chills.
