Is it possible to make player play an animation on clicking a brick?

so i dont want anyone to write me a script or animate anything, im just wondering it is possible.

k so ive got this script

script.Parent.ClickDetector.MouseClick:connect(function(player)
    local leftMouseDown = true
    player:GetMouse().Button1Up:connect(function() 
        leftMouseDown = false 
    end)
	wait(1)
    while leftMouseDown do	
        player.leaderstats.Gold.Value = player.leaderstats.Gold.Value + 10 
        wait(1)
    end
end)

would it be possible to within the

    while leftMouseDown do	
        player.leaderstats.Gold.Value = player.leaderstats.Gold.Value + 10 
        wait(1)
    end

Part add a player animation. ill explain
