Great prop. Nice a big guy. I’d use a heat gun to remove the hot glue from that area and then you can recheck the connections with the red and black wires. Not sure if that black one needs to be resoldered. Also the connections around the LTK5130 audio amplifier chip look a little yellow light that might be fried. Let’s see if anyone else knows this prop and can help you out.

Fundamentally, it looks like he moves his head back and forth, the eyes light up, and there’s some audio. If you can’t repair the board, you can figure out the voltage requirements for the head movement motors and the LEDs and then build a separate system to power those separately.

Think there's any chance a speaker shorted or dropped the impedance significantly? That little chip does look toasty, I wonder if it has short circuit protection built in or not, you know? I typically expect speakers to go open circuit like losing a wire but maybe there's rodent damage or corrosion/rust or highly conductive spider webs (JK on the last theory, but wouldn't that suck if it was a thing).
