In Baldo The Guardian Owls, you can use your Guardian Horn to play the Owl Song in front of scarecrows. They will awaken and give you presents. Scarecrows can be found at the below locations.
Rodia Town
This scarecrow can be found just before the bridge leading to Rodia Town!
Pansa Hills
This scarecrow can be found behind a house (that has a chest containing 50 Dindi in the basement!). From Maneko’s house, follow the path a short way west to find a map transition. Continue heading west, sticking to the south side to find the house!
Leone Heights
This scarecrow can be found in a snowy field in the southern part of the area.
