Ah yes, Japanese drinks. My friend had the unfortunate experience of having to drink said drinks(a canned bottle of Calpis) where he had to shake it 10 times before he could drink it well. He said it was milky, sticky and taste terrible.
We all made fun of him later but he didn't seem to understand the joke. It was immature but hey, that's what made it all the more fun.
Despite finding the actual item being parodied, the ingredients list doesn't match up enough for me to decipher the more scrawly/cut-off parts, so I'm just leaving that be.
Ah yes.. The canned drink with something in it that need to be shaken well.. I've had a can of grass jelly drink, and i didn't shake the can at all.. Boy oh boy did i spend some time trying to get all the jelly cubes..
