Things to do in Sapporo!

Hi, I'm currently in Sapporo and I dont really know what to do tomorrow (13/3). We've visited the few common places:

Niko market Mt Moiwa AOAO Aquarium Tanukikoji Shopping Street Nakajimakoen Park Susukino

We intend to visit Sapporo tv tower and maruyama park tomorrow but other than that we don't really know what to do, we've done day trips to Otaru and will be doing a few more day trips to Noboribetsu, Biei and Furano, any other ideas would be greatly appreciated!
