3D Animation Loops I like

Was looking for creature animations but didn’t find any in the style I was looking for. These are both in the style’s I was thinking about but with objects and a seemingly sentient sphere. The first intrigued me because it was a simple concept but that it reconfigured the walk cycle of the character every time it went through a door. The second one struck me with its simple animation of a sentient machine. It seems happy with all the bright colors and literal smiling faces being produced but the eyes on the machine seem to blink in pain every time the loop ends.
