Over the years, I have been given several miniature penguins. They are all cute...and fragile. You probably have some sort of tiny treasures of your own, so here's a way you could possibly display them.
Gather some larger stemware. If you don't have any, you can pick them up at sales or thrift shops for just a little money. These were a quarter each.
Invert them and place your figurines within.
I stuck this trio on a shelf next to the fireplace, added some greenery and put candles on top. The penguins will be on display throughout the winter.
If you prefer, you can make your display a little more permanent by gluing the figurines to a piece of foam core and then gluing the rim of the glass to that. My sister and nephews created this one for me several years ago. Although it's tough to see, it has boys sledding with a snowman and a little Boston terrier dog!
Have fun if you try it!
