Hello. I would just like to suggest a new celebration creature.
you could have a Banana flying across the screen when task have been completed. it could be the “asana banana”. 
one option is to have it dancing, like the old internet meme. The second option is have it in a cape and eye-mask, as if its a little super hero.
oh well, it was just just an idea. 
A very creative idea, indeed! 
Don’t forget to vote for yourself, @Danylo_Motyka !
I’m no sure it fits in with Asana’s ‘sentient’ mystical creatures though, so it doesn’t get my vote, sorry! 
I’m making up for @Richard_Sather’s rare non-visionary moment and voting for the masked and caped banana (who ideally would dance but only randomly). Just hoping the yetis and narwhals don’t eat them!
