My brave triceratops!

I was level 21preparing to rid my home of 1 of 3 therizinosaurus, remarkably I took like 3 minutes to get ready! I hopped onto my house placing a wooden spike wall for it to get hurt by, I shot a arrow at it to aggravate it but it hit me off my wood home and I got it to 480 health until it killed me, when I saw Ember(my trike) fighting the beast! She killed the therizinosaurus but her health was 76-79 and I took the therizinosaurus claws out of her inventory surprised and excited.
