On Bamboo Day you celebrate pandas, bamboo, relaxation and time with your friends and family, as is the lifestyle of pandas and bamboo. You use everything you have with bamboo, or buy things with bamboo if you don't have any (I have a bamboo lamp, a bamboo tiki torch, a bamboo staff, etc... and a bunch of bamboo in my back yard which we make the BAMBOO DAY TREE out of!). Also, you order/go out to eat Chinese food, which is yummily appropriate.
If you guys tell me that you celebrated Bamboo Day I will post a new chapter. I swear to it. So get your panda on!
