local players = game:GetService("Players")
function touched(otherPart)
local partParent = otherPart.Parent
local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
if humanoid then
script.Parent.Size = script.Parent.Size + Vector3.new(1,1,1) --The size it will grow once touched
end
end
script.Parent.Touched:Connect(touched)
i would be happy if you could explain where the debounce should be and how to add it

now it wont grow like before but thanks for trying :)
it should work but your code is the problem if you want to add debounce you would have to do it differently but you have the basics of the debounce with the if statements
