I played Grizzleheim for like ever until my friend told me it wasn't required! I spent a lot of time there. Maybe you could put a sign or something that says 'Not Required' because I could have been in Celestia a long, long, long, long, time ago! Also the bosses are VERY hard in some parts. Some as hard as Celestia. I mean REALLY! Why! I thought grizleheim was as easy as Krokotopia. Plz right back. Thanks for reading! :D
