Whishlist: Arctic/Tundra/Taiga exhibit animal

[Ngalamashterino]

I am currently building an Arctic Tundra/Taiga zoo but I discovered that there aren't any exhivit animals for those biomes. So I got to thinking, what exhibit species could they add for those biomes.
My suggestions:

• Lemming (favorite is the Norway Lemming)
• Red-Garter snake
• Blue-spotted salamander
• White Mountain Fritillary butterfly

Any more suggestions?

European adder: most northern accuring snake in the world
Wood frog: These are the ones that freeze over in winter and thaw out at spring perfectly fine

 

[Cynogale bennettii II]

The viviparous lizard seems like a good option, as they are the only lizard to occur in the Arctic Circle.
