Laughterblast

Laughterblast is a fuzzy yellow wolf, the animal counterpart of Nobita and, just like Nobita, a comic relief and source of laughter.

Personality
You could literally just copy and paste Nobita's page for this section (which is what I did)

Exactly like Nobita, Laughterblast is hyperactive, excitable, quirky, and outgoing, often speaking and acting in non sequiturs. He loves to meet new people and make new friends, and loves to make others smile and laugh.

Laughter sometimes has a lighthearted manner in serious situations. As a result, he is often not taken seriously by others, who occasionally call him out on his seemingly illogical behavior. But Laughter's lightheartedness often turns out to be right as the situation they are in later turn out to be a fluke, or just some simple problem needing a simple solution. Whenever they are in actual danger, Laughter's craziness vanishes and he seldom fools around, instead he rather tries to figure out a way to save them.

Laughterblast is also the king of randomness, doing completely out-of-the-blue random things here and there, appearing at random places like an air vent or somebody's locker, or even inside a bedroom cabinet, and saying random things which make people stare. He is also known to frequently shatter the fourth wall and stare directly or smile at the TV screen or camera, as if he could see the audience watching him.

Behind his hyperactivity, randomness and insanity, Laughterblast's big heart and kindheartedness do not often get the chance to come to the fore, but deep down he is simply a kindhearted, good-natured and "nice" boy with a huge willingness to help others.

Physical appearance
Laughter has bright yellow, fuzzy and rather rough fur with straight smooth black fur shaped like hair on his head. His tail is extremely long for a wolf's, and is as rough and fuzzy as his fur. He wears big, round glasses just like Nobita's and has light blue eyes and a brown nose.

Appearances and depiction
Laughterblast debuted in the 2015 series as Nobita's animal counterpart. Laughter and Nobita first met inside an AC vent, where they both had gone "to hunt for treasure and pirates". They hadn't expected to see each other there however, so it resulted in them both screaming and falling out of the vent on top of Suneo.

Laughterblast is a prominent character in the film Blazers Aboard!.

Trivia

 * Laughterblast's name has been officially stated to be spelt as one word, however Laughter himself contradicts this in the show when he states jokingly; "Responsibility is my middle name! Laughter Responsibility Blast.", indicating the name might be two separate words.
