Its like reading the movie in manga form but cause of space and limitations corners are cut. Including one of my favourite bits. The bit cut ->

When they are banished to the arctic instead of going off and meeting the yeti/snow guy, sully realises they forgot to turn the door off and they just turn around and go back through. Ngl I laughed at the absurdity cause it felt silly but dang was I sad to not see it in the manga
