Pegasus by Mattel - a great companion for the careful ones
This toy became very expensive in the last few years because it's so rare: 20 Dollars in 1997 to ~ 150 Dollars. But it's still just a plastic plaything with rough seams and thin boards. Perhaps that's why it became so rare. The white plastic becomes yellow in the sunlight but stays cremewhite in the box.

The wings move by putting batteries inside; otherwise they stay still. They are removeable also so you can choose the sides (on the one side with a blue stripe, on the other side unicolored.
