How to make random Models spawn around the map?

Hello, I am making a game where random models spawn around the map, I have already created the selecting service but need help making it spawn anywhere in the water of the map. Heres the script:

THIS IS A MODULE SCRIPT

--[[

	Name: Trash Generator
	Description:  Generates and Spawns trash
	Author(s): Axyanz (@Axyanz)
	Date: Mar 12 - March 12th 2022 @ 3:05

]]



-- Values --
local Trash = game.ReplicatedStorage.Content.TrashCollection
local blacklist = {}



-- Generating System:

local function selectTrash()
	return Trash:GetChildren()[math.random(1, #Trash:GetChildren())]
end


You’d clone whatever Trash was randomly selected and parent it to the workspace container.
