Everything I understand about undertale. Lol

I AM GOING TO SAY ALL STUFF I KNOW ABOUT UNDERTALE IN MY PERSPECTIVE/KNOWLEDE; THERE IS LE SKELETON SANS WHO HAS BONE POWERS AND SAYS SO MANY JOKES THAT HIS BROTHER SKELETON ID SNNOYD FROM HEARRING HIS JOKES; THEN A FISHY PIRATE(?) AND DINOSOUR SCIENTIST(?). I HAVE NO IDEA WHAT THEY DO. AND A GHOST THAT CRIES OR SOMETHING. THERE IS THIS FLOWER THAT IS EVIL(?) I AM VERY CONFUSED WHY LE FREAK IN BRICK THE FLIWER TURNS INTO ABOMINATION; YOU FIGHT AND BEFRIEND PEAPLE/MONSTERS IN DA CAVE OR S O M E T H I N G; THE ONLY THING THAT GOT MY ATTENTION IS THAT THE GAME BREAKS A FOURTH WALL WHEN FISHY PIRATE(?) STARTS LATER IDK WHERE TALK; YOU PLAY AS CHARACTER CALLED FRIZK (I THINK) AND AFTER I FALL IN HE OR SOMETHING YOU GET ADOPTER BY HUMANIOD GOAT; ANYWAYS DO NOT SPOIL TO ME ANYTHING BECUSE I WANT TO PLAY IT FIRST
