Bud Grouse

Mr. Grouse is a supporting character in The Loud House.

Biography
He is the grumpy next-door neighbor of the Loud Family, and he seems to get along well with them, and after "11 Louds a Leapin'", he and Lincoln are friends. Like the Louds, he also has a big family, but lives far from them, and lives alone.

He first appears in the episode "Chore and Peace", but his name wasn't revealed until "A Tattler's Tale". Not much is known about his past, but we know that when he was a child, his hair was brown, and he still wore glasses.

In the episode "Lock 'N' Loud", it is revealed that he's allergic to walnuts.

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 noise and messes.

He is usually unhelpful when Louds ask him for a favor. He agrees to help only when he gets food in return like lasagna or muffins.

It appears that whenever the Louds (possibly anyone) involve him in a plan, he'd usually explain the plan out when something goes wrong, as seen in "Lock 'N' Loud", when he said next time if he was going to pretend to be robbed, the muffins should not have walnuts, and in "Garage Banned", he also accidentally said that he crashed into his own garage instead of the Louds' garage.

Appearance
Mr. Grouse is a heavy old man. He doesn't have hair (except for the two hair strands that he has on his head), but he has a white mustache.

He wears a white shirt under a black waistcoat, a blue tie, brown pants, and shoes. He also has a golden pocket watch in his waistcoat's right pocket, and a pair of little glasses.
