There's no time limit on choosing a tribe name because that's easily updated and doesn't affect the scoring.
I've been trying to think of names for your tribe, going with the lollipop theme, but the first ones that come to mind don't speak well of your tribe. lol!
Survivor Suckers
Lolligangers
Looking at the Candy Warehouse website, some of their lollipop and sucker names might work for an interesting tribe name:
Psychedelic Swirl
Squiggly Pops
Rainbow Pops
Unicorn Pops
How about inventing a new variety of lollipops based on your associated tribe? Call them Buffalo Pops.
