Script: [script.Parent.MouseHoverEnter:connect(function(MHE) local Player = MHE local Mouse = Player:GetMouse()

local topText = "Sorry," -- the text that'll be shown in the top TextLabel
local bottomText = "Can't enter without a code from our boss. His name is, ehhh imaginevrething?" -- the text that'll be shown in the bottom TextLabel

if Player.PlayerGui:FindFirstChild("MouseTip") then
    Player.PlayerGui:WaitForChild("MouseTip").MainFrame:TweenSize(UDim2.new(0,250 , 0,125), "Out", "Quad", 0.2)
    Player.PlayerGui:WaitForChild("MouseTip").MainFrame.Top.Text = topText
    Player.PlayerGui:WaitForChild("MouseTip").MainFrame.Bottom.Text = bottomText
else
