Found this complete set of 4 Hamtaro toy set-- made in 2004 for McDonalds at Taiwan.
These happy meal toys are so much better than the happy meal toys in the U.S. I had thought that these four were going to be tiny- 2-3 inches maximum, but turns out they are far bigger than that. The hamster figure itself is 2'' tall.
And the Ferris wheels and seesaw all have a winder of its own and actually spins :) I only opened the Hamtaro and Penelope one for my sister, the rest of the two I'm keeping xD (Pashmina fan).
