Y is for "You Have Twenty Seconds To Comply!"

Nine, Eight, Seven . . . 

 

It's a black, white-button toy, which is yellow and red! Which reminds me of a joke about a well read newspaper, carried by a Zebra killed on a pedestrian crossing!

 

 

 

That's it, an unknown maker, pocket-money toy robot/mech/power-loader, unmarked, with extending arms, although they are of fixed length and extend by rotation at two points of articulation, per limb. Dead cool!
