Songs about working together as a team/fitting together?

Hey folks, I’ve been gone from Fluther for what feels like FOREVER, but i’ve come crawling back because I need help and I know Jellies are reliable folks…
I work at a summer camp and the theme this summer is “piecing it together” and our focus is on working together/parts becoming a whole/etc. but we’re really struggling to find a happy, upbeat, child appropriate song that we can use as a theme song for the summer! We’re ideally looking for songs with the same message as “we go together” from Grease or “All in this Together from High School Musical, except without the sound where we’d want to tear our own ears off halfway through the summer. So, here I am begging for suggestions. Please and thank you!
