Waddles

Waddles the Pig is Mabel's pet pig. She won him at the Mystery Fair in "The Time Traveler's Pig."

History
Waddles' first appearance is with Mabel in the opening credits, where Mabel is hugging him. His official series debut is in "The Time Traveler's Pig", where Mabel wins him in a "Guess the Critter's Weight" game. She looked for a suitable pig when one said something that is either "Mabel" or "Doorbell." The pig, originally named "15-Poundie", was renamed Waddles (because he waddles when he walks). The bond between Mabel and Waddles is strengthened each time the twins travel through time, resulting in her spiraling into depression when she loses him to Pacifica Northwest in the only successful Dipper timeline. After realizing how much Waddles means to her, Dipper goes back in time and sacrifices his chance with Wendy to allow Mabel to re-win Waddles. To show her appreciation, Mabel sends Waddles to retrieve the caramel apple Robbie is sharing with his new girlfriend, Wendy. This startles Robbie, causing him to drop the apple and knock over a barrel of hot water, painfully shrinking his pants. In Fight Fighters, he sits next to Mabel as she plays a card game with Grunkle Stan and before the fight asks if they want her to send Waddles on Robbie again, referring to The Time Traveler's Pig he is also there when Mabel watches Grunkle Stan while he watches TV. At another point he sits next to Mabel at the table while Dipper worriedly paces about his upcoming fight with Robbie.

Appearance
Waddles weighs 15 pounds. He is pink with darker coloration around his left eye and spots on the left side of his back. He has a rather plump face. His favorite food appears to be caramel apples.
