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.

Moving here was easy... the problem is staying alive!

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