I guess noone has any doubts about that!  ^_^

- Those Happy Blue Creatures are As Kind, Friendly & Small as Trolls & they Like to Sing & Dance! 

And Most of them are Optimists! 😁 ( there was only one 'Branchlike'... - his name was Grouchy, as far as I remember!  ^_~ )

Seems that not only I had the idea about making friends with Smurfs - because I found some fanart of both Trolls & Smurfs in One Picture. All the drawings made by Trolls & Smurfs fans looked good. There was Poppy meeting a Smurf in one drawing I saw, Satin and Chenille meeting a Smurf in another one - & Me greeting a Smurf in this one: 

( I also added this drawing ⤴ to my 'Thank You For Your Fanart' book - because I liked it Really Much!  ^_^ 👍 )
