Toy to occupy baby in flight

Hi all, so we're planning to fly around 19 hours at the end of the year to move back home, baby will be 6 months. Any recommendations on toys or activities or anything to help keep baby occupied during the flight? It will be a 4.5 hrs flight + transit + another 11 hrs flight.

Right now he loves crinkly and colorful toys, also loves chomping down on his teethers and touch-feel books. The thing he loves the most is talking to us and playing during tummy time, which will be tough on the plane! He really loves to be on his tummy and rolling around.

Thanks!

P.S he's not a good sleeper so I don't expect him to sleep a lot during the flight 😂😭
