click one of the buttons to read, and press the X to close out. One of the popups has sortable words. (click and drag) When you press the left button, it triggers a custom block called "This block literally does nothing" The definition of that block is that block. If you're confused, look at the code. (the block is actually there, but as a joke)
Credit to Mrs. Focacci for *cough cough* giving me the assignment. (the cough cough was a joke, don't take it as me being rude)
