This may be similar to the episode "Zoey at Day Camp" from Zoomer Life.
Before the closing Megamix, DJ Lance and Kemba recap the episode and say "Now it’s time to dance. Are you ready? Let’s do it, break it down!". After the Megamix ends and everyone cheers, Kemba already disappeared.
After Megan and Peyton do the cool trick, the off-screen singers don't shout, "Cool tricks, cool tricks!" and Megan and Peyton don't greet themselves again.
