#The citizens probably practice some kind of math-based religion if I had to guess

[yjhgvf]

Team Umizoomi canonically has a church/cathedral/religious place and they call it the Bell tower methinks (it's in an episode called Umi city Treasure Hunt if I'm not mistaken)

I wonder what sorta religion Umi citizens worship...

There's a lotta nature themed stuff in the glass thingies like a toucan and flowers and the moon and fruits, but for some reason there's also like a slide or idk a playground?

Umi City Treasure Hunt DOES indeed feature a church-like building that they call "The Bell Tower".

It very much does resemble a modern-day Christian church, but I assume that they didn't call it a church because not all countries the show airs in would recognize it as a religious building.

And there are indeed non-religious stained glass artworks present inside (here's the close-ups they show in the shape magnet segment)
