When casting the spell, you can't be scared, tired, or angry, because whatever emotion you are feeling is the emotion it will feel. Instead, think of a thought that makes you happy and encourage you to keep going in the objective. Next you need to listen to the animal sound in your head and picture it attacking something. If it's a weapon, imagine someone throwing that weapon, swinging the weapon, or whatever that weapon does. But it can't summon any firearms. Which means no guns and nothing that could shoot.
