3D model sources

Bird, earthworm, snake-head and nest source models were created with Meshy. CUCKOO adapts those sources through mesh cleanup and retopology, texture baking and color adjustments, rigging, animation and Unity integration. The nest combines generated geometry with locally built geometry and materials.

Game-specific art & implementation

CUCKOO's branch barriers, delivery nests, golden-worm props and wind leaves were constructed locally for the game's rules and scale. Gameplay, interface layouts, animation integration and store presentation were developed for CUCKOO.

Sound & music

Sound effects and forest ambience were generated with ElevenLabs during the account owner's Pro subscription on 4 October 2026, then edited and mixed for the game. CUCKOO's music was composed and synthesized locally, without external samples or Eleven Music outputs.
