Check on Dina
Once you gain control, head outside and grab the teddy from the tractor, then go back indoors and interact with the record player to put on some tunes, now make your way over to Dina for a short scene.
After you're both done dancing, head outside with Dina and then work on putting all the Sheep into the barn. Here you'll want to walk behind the Sheep and they'll slowly make their way into the barn. Once all the Sheep are inside you'll find one more hiding behind a shovel, go towards it and you'll see a quick flashback, now walk towards the door.
Once the door has a shut you'll need to sprint down the stairs and attempt to open the door to view a cutscene. After the cutscene, walk back into the house to view another scene. Finally, go downstairs and interact with the guitar for a cutscene.
