How do i make the AI spawn a Zombie?

I want this Ai to spawn a zombie when it says something

code:

chats = {“how do i play this game”,“nub”,“help plz”,“im gonna spawn in a zombie”}
game.Players.PlayerAdded:Connect(function(player)
wait(3)
game:GetService(“Chat”):Chat(script.Parent.Head, "hi "…player.Name, Enum.ChatColor.Green)
end)

while true do
wait(6)
game:GetService(“Chat”):Chat(script.Parent.Head, chats[math.random(1, #chats)], Enum.ChatColor.Green)
end

Try this. Just put your zombie model inside ReplicatedStorage, and put this server script in ServerScriptService.

chats = {"how do i play this game","nub","help plz","im gonna spawn in a zombie"}

game.Players.PlayerAdded:Connect(function(player)
	wait(3)
	game:GetService("Chat"):Chat(script.Parent.Head, "hi "..player.Name, Enum.ChatColor.Green)
end)

while wait(6) do
	game:GetService("Chat"):Chat(script.Parent.Head, chats[math.random(1, #chats)], Enum.ChatColor.Green)
	
	local zombie = game:GetService("ReplicatedStorage").Zombie
	zombie.Parent = game.Workspace
end
