Addition to the wooden car puzzle toy, here is another 100yen toy my son loves.
He loves soap bubble, but he cannot blow them well.
He once sucked up the soap instead by accident, and since then he is a little scared to blow bubbles.

One day we were playing at a park near our home, and we saw a boy and his mother playing with a gun-like soap bubble toy.
And I thought it might be something we could buy at 100yen shop nearby.

So, next day we went to Seria and found it!

It's 100yen and it comes with a plastic tray and soap, but no battery.
You need one AA type battery and a + screw driver to put it in.

You dip the gun muzzle into the soap fisrt.
And by pressing the button on this gun the fan turns and with the fan wind bubbles will come out.
My son was 2 years and 3 months when he started to play with this toy.

In the beggning he was awkwardly pressing the button with the other hand, but soon he got to be able to hold it and press the button with one hand.

I guess it's not that strong, so the first one we bought broke for some reason.
So, we bought 2 more of them just in case.

And, the size of the tray is just the same as the gun muzzle that he often flip it and spilled the soap.
So, we are using bigger size tray instead.

My son loves many kinds of toys, but this one has been definitely one of his favorite for a long time.
