Each biome spawns 1-3 creatures per chunk. Creature behavior is seeded by the Bitcoin block nonce — new block = new movement patterns.
Sheep MOUNTABLE
Wanders plains in wool colors, occasionally hops happily. Mount with E to ride.
Body made of textured wool material. 10 color variants.
Monkey
OCM-style monkey with expressive face and swinging arms. Scratches head when idle.
Scorpion MOUNTABLE
Giant desert arachnid with curling tail and pincer claws. Tail wags ambiently and rattles violently every 6-16 seconds. Mount with E.
8-legged with 2-pair walking animation. Tail is a hierarchical chain of 5+ segments.
Penguin
Small waddling bird with orange beak and feet. Occasionally throws snowballs that arc with gravity.
Snowballs have realistic gravity + rotation and despawn after falling far enough.
Fox
Slender creature with white tail-tip. When player approaches, 60% flees, 40% stays brave (ignores player for 3 seconds).
Wizard
Purple-robed figure with pointed hat, beard, and glowing staff. Periodically emits magic sparkles from the staff orb.
Magic bursts spawn 3-5 colored particles with physics-based fall and fade.
Alien Jellyfish
Translucent glowing dome with trailing tentacles. Floats above terrain with a gentle bobbing motion.
Tripod
3-legged alien walker with a single large glowing eye. Legs move in offset rhythm creating an eerie wobble.
Drone
Cyberpunk flying machine with spinning rotors and red eye. Patrols in straight lines with 90° turns. Periodically emits a cone-shaped scan beam below.
5 color variants. Scan beam fades in/out over ~2-4 seconds with pulsing opacity.
Sentinel
Large stone head with glowing orange eye sockets. Slowly rotates to face the player when within 16 blocks. Does not move.
Wraith
Translucent cloaked figure with glowing white eyes. Pulses opacity and sways like a ghost. Drifts freely across terrain.
Anglerfish
Bulbous fish with jagged teeth and a glowing yellow lure dangling from its head. Lure sways and tail wags as it swims.
Blue Jellyfish
Ocean-colored translucent jellyfish. Drifts slowly, tentacles sway.
Cat
Compact four-legged creature with triangular ears and an upright tail. Spawns in plains and enchanted chunks (45% / 40% chance per chunk). When the player walks within ~12 blocks the cat tends to trail along about 2 blocks behind — the inverse of the fox's flee instinct. Occasionally rolls aloof and ignores the player for a few seconds before re-rolling. Sits still and tilts its head when idle.
75% follow chance on detection; 4-8 s aloof cooldown otherwise. Cat is bound to its spawn chunk, so following stops at chunk boundaries — walk back in to pick it back up. Six palette entries in plains (black, orange tabby, white, gray, dusty brown, fawn), five in enchanted (black, two purples, lavender, white). Belly fur auto-lightens by +30 in each channel for a free two-tone look.
Frog HOPS
Wide, low-slung body with bulging eyes on top of the head and a permanent grin. Spawns on shoreline tiles — surface just at or above the waterline — in ocean chunks (60% per chunk) and occasionally in plains chunks with a nearby pond (18%). Hops in clean arcs when moving; back legs do the work, front legs barely move.
Pepe-coded green palette. Spawn picks up to 8 random local positions per chunk and keeps the first whose surface Y falls in [WATER_LEVEL, WATER_LEVEL + 3]. Frogs stand on regular ground (no water-surface levitation). Hop arc is a positive half-sine layered on top of the ground-tracked Y.
Vulture FLIES
BlockForge's first natural-flier creature. Dark feathered body, bald pink-skinned head with hooked beak, two amber eyes, wide spread wings. Circles slowly 14–20 blocks above the desert surface on a banking turn. The orbit's centre drifts every ~25 seconds so it never traces exactly the same loop. Spawns in desert chunks with 35% probability.
Circle radius 6–10 blocks, angular speed 0.35–0.55 rad/sec. Wings flap on a slow sin cycle even mid-glide. The body banks ±0.22 rad (~13°) into the turn direction so the silhouette reads as a soaring bird rather than a hovering drone. Floater AI path, no per-tile collision check.
Glitch Hound CYBERPUNK
Wolf-sized cyber-canine with sleek black plating, neon spine accent, and a single magenta forehead LED. Walks in a predator's brisk straight-line stalk, then signature "glitches" — body flickers through cyberpunk neons + horizontal jitter as it teleports 3–6 blocks to a new spot. Sometimes fires the Cyberpunk biome glitch emote in place. Spawns in cyberpunk chunks with 40% probability.
3-state machine (idle 3–8s, walk 1.8–3.2s, glitch 180ms, ~15% chance to instead fire a 1.6s emote in place). Walk SPEED 3.2 b/s. Teleport mid-phase snaps position + facing; accent emissive material strobes through the same neon palette as the Cyberpunk Identity glitch emote so they share a visual beat.
