Continuing on his journey, Sprīdītis makes his way into a forest where he finds a group of children running from a giant named Lutausis (Miroslav Moravecs), who traps the children in a cave. Sprīdītis confronts Lutausis and makes him dance by playing the flute. Defeating the Lutausis and forcing him to free the children. Afterwards, Sprīdītis is met by the Forest Mother (Mirdza Martinsone) and is given a magical stick.
Sprīdītis eventually gets caught in a storm and seeks shelter at an old house. He bangs on the door and is let in but received coldly by a pair of Scrooges. Sprīdītis wakes up in the night to a knock at the door and answers it to find an Old Man (Alfred Videnieks) seeking shelter. Sprīdītis lets him into the Scrooges' home and they get mad and demand the Old Man leaves. The Scrooges put Sprīdītis through trials, where he holds glowing hot coals and where his hand is pierced with a giant needle but the Old Man heals both wounds. Then Sprīdītis uses the magic stick to make trap the Scrooges in the basement. For his help, the Old Man gives Sprīdītis a magic ring and disappears.
Sprīdītis leaves and makes his way to the kingdom. As he is watching a play, the King's Messengers arrive and read a decree from the King looking for a Hero. Sprīdītis offers to help the King and is brought to the Castle. And then the Devil's messengers arrive to prepare for the Devils arrival.

But Princess Zeltīte doesn't want to marry Sprīdītis and goes to find the Witch (Antra Liedskalniņa) to take care of him for her. Though, the Witch runs away and doesn't harm Sprīdītis.
In the end Sprīdītis uses the magic ring to turn himself into a bird to travel all the way back home. In his final act he stands up to the King. The King also takes the Evil Stepmother with him. After all the action and adventure he came to realize that what really brought him happiness wasn't the promise of strength, power, or wealth but was being at home with his family.[2][3][4][5]
