I'm not an expert but I believe it says all across the top "don't dream about this when you're high"
Well, I was not high when I snap picture and I know I wasn't dreaming. Something about this reminds me of the cartoon Gumball, especially the guy on the left. The one on the right kind of reminds me of an orange m&m.
The bright colors are what struck me the most, though I never did figure out if those are letters between the two characters or what. I tried to figure out what it might say but I couldn't make it out.
