My English assessment because I'm dumb

Part 3

Next thing we know,we're spiders? At least we were back at the house where we met Kim k. We were in a attic so we decided to investigate it. Luckily,we transformed back into human after 10 minutes of searching. We suddenly heard a massive growl. It was followed by massive,heavy footsteps. The light flickered on and we recognised exactly who it was. My uncle. He was brainwashed by Kim. He started mumbling something about her as he proceeded to fling us to the other side of the attic,our weapons still held tightly in our hands,except for Lilly,who left hers as we were eating in Antarctica. "DANG IT" she yelled furious but then she grabbed a rake and continued mumbling "this will have to do." Katie leaped towards him and kicked him in the chin,then stabbed him in the top of his left shoulder. Then he ate Katie and blew him out of his ear,blasting at speeds the world has never seen. "Ew" Katie groaned as she got back up again ready to fight,shaking of the drool and mouldy earwax. Ava and me drew our swords and pierced his skull. My uncle Shrieked in horror as he experienced the most pain known to man kind. My uncle seemed to be extremely weak after that as Lilly was yet to attack,trembling with the rake in hand clearly scared,yet unsure what to do. Me,Katie and Ava wrapped him up I'm some duct tape we found in a old box filled with rusty nails. We temporarily had my uncle taped down. But not for long. Katie quickly made some armour out of nails for 2 of us,Katie proceeded to give the armour to herself and Lilly,hoping Lilly would help. Then,Katie rushed to the Christmas box,proceeding to make swords from Christmas trees. Katie and Lexie finished the job by stabbing my uncle in the neck and he returned to normal,shrinking to his normal size.
