My yard, my property!

—"11 Louds a Leapin'"

Bud Grouse[2] (first credited as "Neighbor"; more commonly referred to as Mr. Grouse) is a supporting character in The Loud House.


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

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 it is revealed 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.


Bud 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 the 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.

Despite his grouchiness, it was shown that in "11 Louds a Leapin'" that he can be sincere and kind to others and that his grumpiness might stem from envy toward the Loud family, due to him not being able to visit his own family, which is just as big as the Loud family.


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

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

In The Loud House Movie it's shown that he had brown hair, pair of glasses, a blue Hawaiian shirt with red flowers, brown pants and brown shoes.
