Tips:

• you can SPACE through the dialogues (without making Horse bite with L.Click)
• bite Thistle Tops with R.Click, start with central low one, then to the right, then others biteable
• to enter the Portal to the River scene hit the Singing Vines, following the Bird's sequence 2R-1L; 1R-1L; 1L-2R (here you can find the gif with the solution to the sound puzzle)
• if you feel that you have to reach something (like with vines) after the River scene, use Neigh move to hit whatever sways there
