How do I recreate Lego stud water for a render in Fusion 360?

Hi there

So I need to get this project down for a rendering of a Lego figure being chased by sharks and I really want to use clear blue Lego studs for the water but I have barely any experience using Fusion 360 (I've only ever worked with Solidworks). I still need to model the parts but I was wondering if there is a way to have randomly placed Lego studs on a 8x16 build plate with invisible walls on each side holding the studs in place (see attempted sketch and ship in bottle inspo). I just want to know if its possible to do something like that in fusion 360. Thank you!
