The thing wasn’t completely dead though, but stuck on same tune. Pressing its buttons lead to very brief halt and restart as did switching between English and French. Also the farm scene was stuck and wee man on tractor was static rather than merrily rotating round scene.
Obviously this was going to be more complex inside than toy #1. On opening up there were a variety of PCBs and a motor unit. Testing the switches, motor, lights and mechanics revealed no obvious problems. Reassembling it got the wee man rotating and tune working but I could not resurrect the interactive component. I guess that this probably means the chip/main PCB is duff. Admitting defeat I stripped it for parts (couple of switches, electrolytic capacitors, transistors, a light (or maybe IR) activated switch, the 6V DC motor and its gearbox, pair of PCB-mounted LEDs, and a ton of screws) and consigned the remains to the recycling bin.
So 1 for 2 on toy fixes, the next is pure carpentry so I’m hoping to pull back my success rate.
