Something big has arrived!
We’ve always known Wauwatosa has huge things happening, but our new troll takes it to the next level! Thomas Dambo, a Danish artist who uses recycled materials to make masterpieces, created another spectacular and one-of-a-kind troll, featured in Firefly Grove Park. These trolls are located throughout the world, each one with a special personality. There are over 150 trolls scattered across the world, with more than 40 located in the United States. We are proud to share that our troll is the first in Wisconsin! Nestled in Wauwatosa's newest park, the troll is just one of the many whimsical and artistic features in Firefly Grove Park that you need to see to believe!
Visit Our Troll in Firefly Grove Park
On your way into the heart of Firefly Grove Park, a sweet troll is waiting to meet you. Giant repurposed lamp posts light the way, although a few have gone missing...Mama Rosa will happily give you a whiff of her flowers, although they might not smell as good as you thought they would!

Mama Rosa
Something funny with these flowers
Some have special needs and powers
There’s no roots beneath these flowers
Rain don’t ruin upon these flowers
Something funny with these flowers
Comes from nothing in an hour
There’s not honeybees, these flowers
Have no honey in these flowers
Something funny with these flowers
Stands all summer, won’t go sour
When the sun’s asleep, these flowers glow
I wonder how these flowers grow
- Thomas Dambo

- Keep their own belongings! When leaving the park, please make sure to take all of your items with you, including any personal belongings, and leave any pre-existing parts of the park.
