I don’t know if should risk my last 100 silver on 1 more shot at the bunny balloon ( I really want pink or sweet but bunny rng has not very been kind ) or 2 new color balloons.
I focused on the new colors of the standard Balloons, so there weren't that many different colors to compete with compared to the Bunny Balloons and the Heart Balloons. Worked out for me though, as I was aiming to get one of each color of the standard balloons and achieved that, trading the spare Sweet Balloon for a plush. I never did get a Yellow Balloon on my own, had to trade a spare Pink Balloon for mine. 2 Purple, 2 Pink, 2 Sweet, 0 Yellow on my own rolls.
