Bud Grouse

Mr. Grouse is a recurring character. He is an elderly neighbour of the Loud Family, and gets along well with them.

Background
Mr. Grouse is first seen in "Chore and Peace", in which he informs to Lincoln that trash men will not take his rubbish, because they are on strike to get paid more.

He later appears in "A Novel Idea", in which he compliments Lincoln's girly disguise, and then later the horse he uses to bring him and his mother home.

11 Louds a Leapin'
In this episode it is revealed that Mr. Grouse stays angry on Christmas Eve, because he can't visit his large family, so he stays alone in his house. Also it is revealed that every thing that falls into his yard becomes "his property". After Lincoln discovers this, when he unsuccsessfully tries to recover his sled, he and his sisters decides to make Mr. Grouse's Christmas more special than before.

That night, as Mr. Grouse snoozes away, he hears caroling outside. He walks over to the door, and sees the Loud family and McBride family singing the song that Luna wrote. When they finish the song, Lincoln presents Mr. Grouse with a present: a bus ticket to see his family. Mr. Grouse is touched by the two family's kindness, that he invites them into his house to celebrate Christmas with him. As the two families decorate the house, Mr. Grouse decides to give back their confiscated items as a sign of gratitude.

The next morning, on Christmas day, Lincoln receives a new sled as a gift, which looks similar to the one Mr. Grouse used to own when he was younger. Curious, Lincoln exits the house and sees Mr. Grouse packing his stuff into a taxi before he departs. Lincoln thanks Mr. Grouse for the gift, but Mr. Grouse reassures that he should thank Santa. As Lincoln prepares to ride his new sled, he suffers and accident, but this time, the sled crashes through one of Mr. Grouse's windows. As Mr. Grouse yells out Lincoln's name in anger, Lincoln quickly leaves the scene.

Personality
Mr. Grouse is the typical grumpy old man of the neighborhood. He doesn't like to see objects from the other neighbors in his yard, so he decides to keep them in his house and doesn't give them back. He can get upset by the Loud family's constant mess.

Description
Mr. Grouse is a heavy old man. He doesn't have hair (except of two hair strands that he has on his head), but he has a white moustache. He wears a white shirt under a black waistcoat, a blue tie, brown pants, and shoes. He also wears a pocket watch in his waistcoat's right pocket and a pair of little glasses.
