Yoto animal icons
The largest set here, and the one most requested, because animals are what a lot of children's audio is about. Faces and side-on full bodies, so you can pick whichever reads better at the size it will actually be shown.
Drawing animal at 16×16
Animals are the hardest thing to draw at 16×16 and the easiest to get wrong. A recognisable animal at this size is mostly silhouette and one or two defining features — a mane, a trunk, a shell. Anything more detailed turns to mud on the player, so these are drawn deliberately blunt.
Every icon here is a transparent PNG at exactly 16×16 — or a GIF, where it moves — so there is nothing to crop or resize. Download it, open your Make Your Own card in the Yoto app, pick a track and upload. Why icons look fuzzy covers what goes wrong when you shrink a photo instead, and how to make your own Yoto icons covers drawing one from scratch.
