How do I make an npc jump if it's on a seat?

Just like in the title. I wanted to know, how do I make something like "if NPC tripped or sits make it jump". I don't want it to be for a player, I want it for a specific NPC. Thanks.

You should want your humanoid to change state. If you want it to be a specific NPC, then put this script inside.

local Humanoid = script.Parent:FindFirstChild("Humanoid")

if Humanoid:GetState() == Enum.HumanoidStateType.Seated then
	Humanoid:ChangeState(Enum.HumanoidStateType.Jump)
end

The :GetState() method is used to find what the current humanoid state is in, the :ChangeState method is used to change the humanoid state.
