We all like Poppy singing 'Everybody, move your hair & feel united' scene cause it's nice, happy & colorful & the Trolls dance together - but my detailed & analytic mind payed attention to one thing: To those 5 creatures ( bugs ) Poppy jumped on & each of them was spittng a smaller one out of his mouth then: 

I took that picture to illustrate what I had in mind - & all of those 5 creatures are visible in it. The Younger Viewers might have just laughed at it - cause it was quite funny... - but when I saw it I started to think: what were all those creatures 'doing there'? - I mean 'What was every smaller creature doing in the bigger one's mouth?' cause the Orange Bug must have caught the small Pink Bug into his mouth first, the Yellow Bug must have taken them both into His Mouth next, then the Purple Bug must have taken the Yellow Bug ( with Orange & Pink ones inside ) into His Mouth - & at the end The Strange Blue Creature must have taken the Purple bug ( with 3 previous ones inside ) into His Mouth... - was that a kind of 'food chain' or what?... - Idk, but 'spitting the smaller creatures out' went in reversed order & Looked Funny... - That's what Counts!  😉
