This reminds me how I got really nice blue-n-white toy robot as Christmas present when I was 4 or 5. It moved forwards with tiny wheels planted in the bottom of it's feet, cute round head that had flashing lights and telescope hands which had working nipper-palms you could open and close.
I named it Tom after this one robot character in 80's UK stop-motion animation called "Wonder Machine Bertha" and I loved it so much that I wanted to sleep with it thou it was made of hard plastic and presumably not very cuddly bedtime toy
When you pushed heart-shaped icon in it's chest it repeated two lines, "I am silly Billy-Bot" and "Oh no, power low!" (or something similar, can't remember anymore)
It used 4 D-size batteries and as with toys usually, once the batteries had been changed couple of times - as I played with it a LOT - my interest of Tom toned down and I forgot it in the toybox or under my bed and ...when I found it again the batteries had leak awfully (D-size batteries leak a LOT) and Tom wasn't working anymore =(
Not so many years ago I found cardboard box full of my old toys and all kinds of random toy parts that usually end up piling in children's toyboxes. And I found Tom's hand laying there along all the other random stuff.
I have been trying to find that same toy from Amazon and Ebay couple of times - so I could buy myself piece of the golden memories of childhood, but I haven't had luck in searching.
And yes, this was totally mega off-topic
