 ### Added
 
 - Hand-drawn `fish/goldfish.png` icon (PR #136) — eighth hand-drawn piece in the library (after sea-bass, koi, ant, coelacanth, frog, robust cicada, brown cicada). 2048×2048 watercolour-and-ink source at `icon-sources/fish/goldfish.png`; exported to 768×768 (88.9 KB) via `npm run icons:export`. Replaces the scraped wiki placeholder. Cross-game routing propagates this to any game that maps to `fish/goldfish`.
+- Hand-drawn `fish/tadpole.png` icon — ninth hand-drawn piece in the library. 2048×2048 Procreate source at `icon-sources/fish/tadpole.png`; exported to 768×768 (24 KB) via `npm run icons:export`
+- Hand-drawn `bugs/agrias-butterfly.png` icon — tenth hand-drawn piece. Replaces the wiki-scraped `.jpg` placeholder. 2048×2048 source at `icon-sources/bugs/agrias-butterfly.png`; exported to 768×768 (62 KB) via `npm run icons:export`. Manifest updated from `jpg` → `png` for this entry
