There are a number of companies who sell snow globes online.

Locally, check card stores, discount and department stores (especially in the holiday decoration section), places that sell tourist items, and artisan shops.

The Universal Souvenir for all countries is a snow globe.
You'll find this item to buy at one of the shops in Monstro City. Items rotate often so you may need to keep checking back.
Retailers will tell you Snow Leopard will not come out until September 10, however, it came out August 28. If you want Snow Leopard now (instead of waiting until September 10), the best thing to do is to order online.
Snow Leopard probably has a feature that lets you use English.

There are snow globes where you can buy them and they have insructions on how to put it in!! So it's your own custom made snow globe. Oh yeh you can also get ones with just one picture slot, or you can get a double sided snow globe, where you can put to pictures in it. Also they make FANTASTIC gifts, for any occasion!! Addition to answer: If you do not want to use a plastic, slot-based snow dome, you can also use a company, such as SnowGlobeCentral, who will accept digital photos and create a custom snow globe to your design.
you buy a proper fish tank ya fool, that's too tiny.
