If you are certain to Face the pigapult, then Bete is usually a great way to stop it down for the entire game, as she will pop once it sacrifices a Pig to shoot, and so you can place her engaging the Pult, making it unable to shoot, and most probably wont be able to disengage her too on its own, so call it an activation lost (and your opponent lost a Pig too!). On Bete's activation, kill its Pig ammo, or any other juicy targets while still engaging the Pult (Slop Haulers/Taxidermist...). Your opponent will now have to waste resources on his backfield to get rid of Bete, slowing him down. Bete is not the most durable model in the game, but as Gremlins most usually target Df, she will be able to absorb some attacks before going down, unless your opponent uses one of his best models on her. Either way, it's a win-win situation. Just be sure to hold a 10+ on your Hand, in order to bury her when she goes down, and then repeat the operation the next time the Pult wants to shoot
