Flag. Use buttons to change ant to wax and back. Ant also exercises, but it has to be a separate project: https://scratch.mit.edu/projects/854040996/
Used blender to render ant animation frames: one for real and a separate rendering for wax. Both animations run all the time, but commands make only one visible. Ant is on turbosquid, but isn't wax. Get a model or make your own, make any changes you like in Blender, then render the model, say an ant, with transparent background into many png frames. Make a separate one with a wax texture.
