Legend of the Three Caballeros S01E07 - Mount Rushmore or Less
The Caballeros, in the middle of a battle with Sheldgoose, are inside George Washington's head at Mount Rushmore fighting against the President's all-stone memories, which have been animated and manipulated by the spark of life that Sheldgoose and Felldrake came to steal. Sheldgoose is ejected out the President's nose and they return to the cabana with the Spark. Xandra decides to go out with the nieces for a "girls' night" entrusting the boys with the spark. Before long, the spark possesses the bearskin rug on the floor, bringing it to life. The bear escapes into the Institute, and the boys need to find it before Sheldgoose. The Caballeros realize the enemy they've been fighting all along is Sheldgoose.
