[EMERGENCY] How Would I Make My Monster Spit Out Fire Cubes At People?

So I am now trying to create a survival/adventure/crafting game a bit like Fantastic Frontier.

But I am currently stuck on a tree monster that spits out fire cubes at approaching players.

Here is my script:

local tree = script.Parent
local hitpart = script.Parent.Hit
local cube = game.ServerStorage.Cube

hitpart.Touched:Connect(function(plr)
    if plr.Parent:WaitForChild("Humanoid") then
        cubed = game.ServerStorage.Cube:Clone()
        cubed.Parent = workspace
        cubed.Position = tree.Mouth
    end
end)

All this does is make a part drop from his mouth... Could someone help me out here?

Thanks in advance!
