You've recently moved to the picturesque and seemingly harmless Forest Town. The neighbors are friendly, the trees are always green, and the sun is always shining. But be careful: this is a town where tragic accidents happen every five minutes. The inhabitants die and revive as if nothing happened, but you, as a newcomer, have only one mission: survive and don't become the next victim.

Characters

Cuddles

The Optimist

A tender yellow rabbit, very friendly, but always attracts fatal accidents due to his naivety. Cuddles' personality is somewhat mixed; on one hand, he can be dangerously mischievous, and on the other, he is one of the kindest, most optimistic, sweet, and affectionate inhabitants.

Flippy

The veteran

A pale green bear wearing military gear and a green beret. He is kind but suffers from PTSD due to his time in the war. While Flippy can be the cruelest and most dangerous when 'Fliqpy' takes over, in his normal state, he is one of the most sociable and kindest.

Disco Bear

The Singer

A yellow bear with an orange afro and 70s disco-style clothing; a lover of disco music and parties. He is self-centered and desperately craves attention. Despite his lack of success in love, his successful career as a disco singer has earned him quite a bit of money.

Giggles

The Kind One

A very sweet and sociable pink squirrel. She always tries to be kind to new neighbors. She has the personality of a young girl, is somewhat shy, and tends to laugh often. She doesn't like Disco Bear, is Petunia's best friend, and is known for being quite environmentally conscious.

Flaky

The shy one

A red porcupine; kind, shy, and socially awkward. Often seen as a coward, yet she is quite brave despite her opposite personality traits.

Petunia

The socialite

A blue skunk with a light blue arrow mark on her forehead. She always wears a flower on top of her head and a pine air freshener around her neck. Giggles' best friend; she shares a similar personality, yet Petunia has OCD regarding cleanliness and order.

Pop

Cub's father

A light brown, adult bear, wearing something like a red robe or smoking jacket, a red hat, and always smoking a pipe. Even though he is somewhat distracted and doesn't pay much attention to his baby son, Cub, it is clear from afar that he loves him. Due to his responsibilities as a father, he is rarely seen interacting with others. Pop is also impatient and becomes easily irritated.

Shifty

Thief

Lifty's twin brother. A kleptomaniac green raccoon with dark green mask-like markings around his eyes. He frequently steals merchandise and products from others with his brother. They also look for treasures, loot houses, or do anything to get rich quickly. Although they have the same gender, appearance, and personality, Shifty is distinguished by wearing a beige-green fedora. Like most brothers, they argue about who is to blame when things go wrong, but they always work together.

Lifty

The other thief

Shifty's twin brother. A kleptomaniac green raccoon with dark green mask-like markings around his eyes. He frequently steals merchandise and products from others with his brother. They also look for treasures, loot houses, or do anything to get rich quickly. Although they have the same gender, appearance, and personality, Lifty is usually the one leading the plans. Like most brothers, they argue about who is to blame when things go wrong, but they always work together.

Toothy

The freckled one

A light purple/mauve beaver with freckles and very large front buck teeth. Friendly to everyone, admires Splendid, and is Cuddles' best friend. He tends to cry more often than others and is impulsive, though can also be mischievous and stubborn.

Handy

The grumpy one

Handy is an orange beaver with amputated arms. The stumps are covered with bandages. He wears a tool belt (holding a hammer and screwdriver on opposite sides) and a yellow hard hat. Despite lacking hands, he is still able to build many things, big or small. Handy gets agitated, irritated, and angry easily, which indicates he has a short temper.

Splendid

The hero

Splendid is an aqua blue flying squirrel with light blue patagium (gliding wings), a light blue/white oval mark on his torso, and a red eye mask. His powers include flight, eye lasers, super strength, super speed, supersonic hearing, super durability, time reversal, and ice breath. He works for the newspaper and wears glasses and a tie to hide his true identity. He is heroic and kind, but often oblivious.

Nutty

The "Sweet" One

Nutty is a yellow-green squirrel with a yellow diamond-shaped mark on his head and a large curled tail that wiggles when he is happy. Nutty has a strong craving for sweets and is addicted to sugar and anything containing it, particularly candy. As a result of his extreme sugar consumption, Nutty is often hyperactive and jittery, and laughs more than he talks.
