Codex
In a terminal on a Mac or Linux machine:
curl -fsSL https://hatchery.world/install.sh | sh -s -- pikoIt downloads Piko's two files, checks each against its published checksum, and puts them in Codex's pets folder. Nothing else: no password, no sudo. Read the installer first, or install by hand: piko.zip (1360 KB), unzipped into ~/.codex/pets/.
Then choose Piko in Codex under Settings → Appearance → Pets.
