[SOLVED] How can I share this variable across the script without global variables?

So this is my most recent attempt at creating my script before I gave up and decided to come on here. My script is supposed to when the player presses the "M" key spawn their mount, and if their mount is out and they press M again it'll be removed. This attempt does not work. I already checked and the event gets fired and received, and the script kind of works. The script will spawn their mount (in this case a snake) just fine, but when the player pressed M again to despawn it, it never worked, that or it did but had a complication. I tried using a global variable for the mount's model, but that made everyone share 1 mount which was not good for my open world game. The attempt you see is where I read I could use the return feature with the variable and it would make it usable by the rest of the script. After this failed, I gave up.

I want to be able to clone and place a different copy of the mount each time and :Remove() it once the event is fired again. Please help!

Server Script:

game.Players.PlayerAdded:Connect(function(plr) -- This adds a debounce for later
	local hasMount = Instance.new("BoolValue")
	hasMount.Name = "hasMount"
	hasMount.Parent = plr
	hasMount.Value = false
end)



game.ReplicatedStorage.Events.MountCall.OnServerEvent:Connect(function(plr) -- The actual function
	local Stuff = plr:WaitForChild("Stuff") -- The folder I keep everything for the player in
	local Mount = Stuff:WaitForChild("Mount") -- A string value telling the game which mount the player has
	local hasMount = plr:WaitForChild("hasMount") -- the debounce mentioned earlier
	
	if Mount.Value == "Snake" then -- Makes sure they own the mount
		if hasMount.Value == false then -- makes sure the mount isn't out already
			hasMount.Value = true
			local model = game.ServerStorage.Mounts:WaitForChild("Snake Mount") -- The physical mount
			model.Parent = workspace
			model.HumanoidRootPart.CFrame = plr.Character.HumanoidRootPart.CFrame + Vector3.new(0,4,6)
			return model -- What I thought would help
		elseif hasMount.Value == true then -- The part of the function I need to share the variable with
			hasMount.Value = false
			model:Remove()
		end
		
		-- More Mounts Slot
	end
end)

I've been trying to solve this all day. I would really appreciate a response. Thanks in advance!

What I came up with was a solution I knew I could've done, but I didn't want to do it because I knew it would take me a few extra minutes. I was able to search for the model with a string value in it which has the .Value == plr.Name and if the string value is the player's name, it moves it. The other issues I've had so far, is if the player somehow breaks the mount ex: pushing it off the map or flinging it. They'll have to rejoin. I'll be switching the hierarchy around on the off chance exploiters find this.

Server Script:

game.Players.PlayerAdded:Connect(function(plr)
	local hasMount = Instance.new("BoolValue")
	hasMount.Name = "hasMount"
	hasMount.Parent = plr
	hasMount.Value = false
	
	local Mounts = Instance.new("Folder")
	Mounts.Parent = plr
	Mounts.Name = "Mounts"
	
	local model = game.ServerStorage.Mounts:WaitForChild("Snake Mount"):Clone()
	model.Parent = Mounts
end)



game.ReplicatedStorage.Events.MountCall.OnServerEvent:Connect(function(plr)
	local Stuff = plr:WaitForChild("Stuff")
	local Mount = Stuff:WaitForChild("Mount")
	local hasMount = plr:WaitForChild("hasMount")
	local MountSpace = workspace:WaitForChild("MountSpace"):GetChildren()
	
	if Mount.Value == "Snake" then
		if hasMount.Value == false then
			hasMount.Value = true
			local model = plr.Mounts:WaitForChild("Snake Mount")
			model.Owner.Value = plr.Name
			model.Parent = workspace:WaitForChild("MountSpace")
			model:WaitForChild("HumanoidRootPart").CFrame = plr.Character:WaitForChild("HumanoidRootPart").CFrame + Vector3.new(0,5,5)
	elseif hasMount.Value == true then
			hasMount.Value = false
			 for x = 1, #MountSpace do
	       	 local mount = MountSpace[x]
				if mount.Name == "Snake Mount" and mount.Owner.Value == plr.Name then
					mount.Parent = plr:WaitForChild("Mounts")
				end
  		  	end
		end
		
		-- More Mounts Slot
	end
end)

And, so far, it works.
