Buck-A-Roo
I think everyone must have played this game at some point in time. You start off with a mule , with all four feet on the floor, you balance bits of the tool kit on it's back, until your mule has two feet on the floor and the bits of the tool kit are flung all over the floor.
It was another game you could play by yourself , or take turns , even better if the other player hadn't played the game before. There were tactics to it, certain pieces would fit on the saddle better and would balance better.
The game itself came in many different forms, even a 'Toy Story ' tie in edition. But the aim of the game was always the same. Sadly the spring broke in the version of the game I had, but my father soon replaced it. After that the items that were slung off the back of the mule would go that little bit further than normal and the mule and base would keel over. Which actually made the game even more entertaining.
