Thank you so much, Jonny64bit!
So, you are the second person to comment on getting stuck in the grass (out of three comments so far. Heh)
Were you stuck unable to move LittleFoot, or stuck not knowing where to go next? You can pick up PatchOfGrass just on the edge of the RockyOutcropping, then carry him to the Garden across the Void, and the game continues through the Fairy Forest to the Dam and finally into the Bedroom.
If it's getting stuck being unable to move, could you look at the Little Foot Gameplay SPOILERS video and see if that helps, showing how to Give an object to sort of "phase" back into the World and be able to move again.
I'm looking forward to playing Getting To Pluto! Congratulations on your submission! We did good...
