why is my character sliding?

hey, so I'm trying to make my characters small and whenever I'm small it keeps sliding me as if there is very little friction. can you tell me what's wrong with my script? thanks:

game.Players.playerAdded:Connect(function(player)

player.CharacterAdded:Connect(function(Character)

    local Humanoid = player.Character.Humanoid

    Humanoid.BodyDepthScale.Value = 0.25

    Humanoid.BodyHeightScale.Value = 0.25

    Humanoid.BodyWidthScale.Value = 0.25

    Humanoid.HeadScale.Value = 0.25

    Humanoid.WalkSpeed = 50

    Humanoid.JumpPower = 100

end)

end)
