How to spawn a random number of pick up meshes upon collision

I am trying to make a water puddle type of blueprint. When the player jumps on the “puddle” (which I will have set as a collision) then a random number of meshes (I have this setup as a pickup for the player already) will appear from the “puddle”. I have some knowledge on UE4 but this is leaving me stumped. Thanks in advance for the assistance.

Something like this:

You could use components, I guess but I think that spawning pickup actors would be easier.

I can try that, thank you for the help. I have pick up actors but I am wanting to spawn my pick up actors from the “puddle” when the player jumps on the “puddle” again thank you for your help. I will try this and post my results.
