Spoiler: Hints

Either R or B can knock the ball closest to the motor
R needs to knock the second and third balls.
Win with R
B picks up the star

Very good B and R cooperation level! The zappers make the gameplay more challenging and I like both the grass and stone pathways being used to get both stars! Great!

Just when I was going to rate the level I saw that you deleted the previous one... so I played both levels... I must say that I completed both levels cleanly, with no problems or shortcuts or inestabilities... this level was a fun collab level, mainly R has more job but B's help is needed ... thanks for sharing @Makl
btw, so glad to see you doing levels again

@ohmytian glad you enjoyed my level. I've got several in the shop right now.
@delator77 thanks. The original was stable, but Mr. Meko Guy pointed out that there were sneaky autopilot shortcuts and that B could be killed and land on the finish.
The modifications just made those no longer viable options.
