Sad/ happy owl
It always makes me sad when the crying owl tells me I am out of hearts. It makes learning a new language a little depressing. Can we maybe get a happy owl when we finish lessons with all three hearts? Not that we need too much praise for success, but who wants to disappoint an owl all the time without a chance to cheer it up?
Thanks for the suggestion! We are thinking up new ways to motivate Duolingo learners.
