Do you have to visit for a certain amount of days in a row to get a bathhouse token? I seem to get everything but.

You get Bathhouse Tokens on day 11 and 21

What did you find in the bathhouse pool? shows all the possible prizes for all days, the cycle starts over from day 1 if you visit more than 30 consecutive days c:

Thank you so much. =)

You also get tokens on days 18, 27, and 29. It's 5 total per 30-day cycle

Could someone please tell me what you do with the various color "special coins"? Colors I have are gold, silver, copper, pewter, red and blue special coins Are they used in the bath house?

Take them and use them here:

Just click on the coin that you have. You can either get sP/items/stat gains on your active pet. Sometimes the coin will pop back out, don't worry you just go back and try again.

The Coin Machine is in the Lower West Side of Centropolis. There's a subway stairs in the lower left corner of the Centropolis map.

Thank you for the info
