This is simple nightlight inspired by Nintendo's Yoshi.
The yoshi model is remixed from the linked source, I designed the Egg in Tinkercad. Looks cool printed in green but some white & red colored nail polish/paint would really finish the job.
Print on his back with this front facing upwards, lots of supports needed. Minimal infill, choose 5% gyroid pattern if available to make the infill invisible. Is kind of a tough print.
