This week--Season Series done, ambigrams to come

So last time I posted my raccoons picture I said that I wasn't entirely satisfied with it and would return to it later. So, for this week I finished the raccoon piece and then combined all four seasons designs.

 

And I found my sketchbooks from just before, during, and just after the mission. I went through them and marked all of the ambigrams or little comics I drew that I want to fix and share, so those will probably be my piece for next week, or maybe the next couple weeks. 

Can you tell what the ambigram on the top says both rightside-up and upside-down?
