Rights holder / original work: Clawd, the Claude Code mascot (Anthropic)
The prizes and the coin-tossing character are Clawd, the mascot of Anthropic's Claude Code. The README calls the game an unofficial fan-made work not affiliated with Anthropic, says the felt Clawd was drawn in code without official assets, and states that the name and character belong to Anthropic and are not covered by the MIT licence of the code. No source shows permission from Anthropic. (GitHub)

About ざくざくラグーン
ざくざくラグーン (Coin Lagoon) is a free 3D coin-pusher game for the browser, set on a beach ringed by palm trees and a lagoon. A big felt Clawd, the mascot of Anthropic's Claude Code, rides a surfboard along the back wall and tosses your coins; coins pushed off the front edge by the moving pusher are yours. A coin that passes through the swim ring spins a slot reel (up to five spins can be stored): matching hibiscus, coconuts, shells or pineapples pays coins, matching Clawds drops a new felt Clawd prize, and three suns start a 25-second Sunset Fever with a sunset sky, coin rain and a faster pusher. Pushing the felt Clawd prizes off the edge fills a collection book of ten kinds, from Classic to the rare Golden Clawd. Side guards are on by default; turning them off in the settings lets coins fall off the sides as on a real machine. When you run low, a coin is handed out every six seconds; the board, coins and collection are saved in the browser. It plays with mouse, keyboard, gamepad or touch, on PCs and phones, in Japanese or English. The README credits planning and direction to たぬ (tanuu5) and development to Claude Code with Claude Opus 5.5 at the MAX reasoning level, and the developer says it took 1 hour 40 minutes from start to publication. Shapes, patterns, music and sound effects are all made in code. Clawd appears as unofficial fan art; the code is MIT-licensed, the character is not.
How it was built
VerifiedThe README credits planning and direction to たぬ and development to Claude Code (Claude Opus 5.5, reasoning level MAX), and says that Claude Code implemented everything from the rule design to the 3D display, physics, music, sound effects and screens, based on たぬ's plan. The felt Clawd is built from distance functions as two pieces of cloth sewn at the edge with a little stuffing, with blanket stitches placed in code. Coin physics use Rapier; a script that runs the machine without drawing it counted side drops, returns and swim-ring hits to set the machine's dimensions, and the look was checked with screenshots from headless Chrome on a real GPU.
- DeveloperDeveloper's note post of 24 Oct 2026: eight browser works made with Claude Code (Claude Opus 5.5) between 9 and 23 Oct 2026; the last of them, ざくざくラグーン, took 1 hour 40 minutes from starting work to publication. — note (たぬ / tank_ai)
Planned and directed by one developer, with Claude Code (Claude Opus 5.5, MAX) implementing the rules, 3D display, physics, music, sound effects and screens. Rendering uses three.js and the coin physics Rapier (Apache 2.0, bundled into the build); textures, music and sound effects are generated in code, and the only external asset is the Mochiy Pop One font from Google Fonts. A Node simulation script can run the machine without drawing it to measure returns and drop rates. The game is built with npm scripts and deployed to GitHub Pages by a GitHub Actions workflow.
