This stand came to me in a daydream at school today
Stand: Don't Worry Be Happy (normally shortened to D.W Be Happy)
User: Huck Everest
Namesake: song by Bobby Mcferrin
Appearance: A humanoid stand with a tropical t-shirt. It's rainbow-colored and it looks like the colors on its body shift constantly. And the most important detail: it has dreadlocks.
Ability: Mind tricks. Causes hallucinations and raises dopamine by copious amounts. The target it's used on will feel so happy that hallucinations will seem like an everyday thing. Also takes away small pains like headaches and muscle soreness.
Edit: The picture up top is what I imagined it'd look like. (I'm also not good at drawing dreads.)
