Those are small animations made for an interactive book of  IBEP, a brazilian publisher. The first song is about a frog living in a swamp and he doesn't like to wash his feet. In the end, he meets a frogfriend and marry her. She likes to knits clothes for them.

The second song is about a tribe of native brazilian folks. They're acrossing a river and are afraid of a giant alligator. In this interactive book, the children can tap the screen of a tablet or an ipad to avoid enemies, make the tribe row fast or put the characters into a boat.
