Don't Overthink

Bonus star for your first level. Welcome to the forum! Cute level and actually a fair use of free-draggables.

Spoiler: My solution using the free-draggables

I used them to carry the zapper bots out of the way.

And so I solved your puzzle with B getting to the win. But you should also be aware that free-draggables that are not contained can cause cheating or other bad behaviour. For example, I was later able to drag one of the free-draggables out of the pool and all the way around and onto the win.

Altogether an easy yet attractive level. I'm going to assign a tag called "4kids" so that it can be found by searching on that tag. I also edited the title above the description to match the one the card so that anyone searching by the title can find it - a good habit to get into. Thanks for sharing!
