you could trade for things that you can buy with momentos (like dreamy party poppers), but those are very expensive atm (a few thousand I think?) and are 40 momentos, so the ratio of TBT to momentos wouldn't be 10:1 (cuz it's a few thousand:40 atm)

likewise, 1:1 tinsel to momentos wouldn't really work either. 40 tinsel is 8 cherries and 400 tbt, but 40 momentos is a few thousand tbt
