For context, that is the Flag and Coat of Arms of Amsterdam.

The toilet is the Dutch/German shelf variety.

The bird is a cockatoo, a Parrot that has a range that includes Indonesia (that was once a Dutch colonial possession.)

Why all three were combined like this?

I have no fucking idea.

It would feel awfully weird sharting on a cockatoo

Why is nothing centered correctly?

It's weird that it's not centered, but that's otherwise the coolest toilet I've seen. You'd have a lot of motivation to keep it clean.

Gonna shit on a parrot 🦜
