A Fairly Odd Summer -

That's a fun premise! A Fairly Odd Summer already leans into time loops, vacation chaos, and magical mishaps. Here’s an you could add: "Wish-Back Echoes" Concept: Every time Timmy, Cosmo, or Wanda uses a wish in the summer setting, it doesn’t just disappear after being undone or expired. Instead, it leaves behind a residual echo — a shimmering, semi-solid after-effect that repeats the wish’s action in a warped, glitchy loop.
