This recipe is by deadinternettheoryistrue on Tumblr! The original text has been kept (with minor alterations) because I think it's joyous and whimsical.

• First, you gotta get a cool cup. I got the one pictured from a thrift store for a very affordable price. But if you can’t find one, a standard clear cup or jar should suffice.
• Now, you don’t need a decal, but I recommend it because they’re cool. I just got some sticker vinyl, traced and cut out the Wii logo and some stars.

Now, for the drink itself!!

• Start by making or buying jelly. If you make it, you should do so a few hours before you intend to make the drinks, as it will need time to set. You can find jelly at most any grocery store.
• Get your cup and add ice and jelly. You should cut the jelly into small pieces or use cookie cutters to make fun shapes. I recommend you don’t add quite all of the jelly, as you’ll need some for the top later.
• Next, add your flavoring syrup of choice, I recommend blue raspberry or melon. You should be able to find them at any restaurant supply store.
• Then, add carbonated water. Flavored sparkling waters also work fine, as they don’t taste like much. You should be able to find some at any store that sells drinks.
• Next add Calpico. This is technically optional, but it tastes way better with it, so it’d highly recommend it. You can get it at practically any Asian market!
• Now, add some ice cream (or something similar)! I use vanilla.
• After that, you can top it with some whipped cream, jelly shapes, cherries, really anything!!
• I would also recommend using a straw to drink it, because you will need to mix it up a bit - but you can’t really mix it before hand, because it will ruin the cool gradient affect.
