Tama p eco town not accessible?

[Yumecantchi000]

I am trying to get a Waltztchi on my tama p using the secret evolution. May I know how to unlock the eco town? Or do I need to see the eco triplets at the park to get there? Thank you in advance!

You need to get an Eco Car from the Eco Triplet in the park
