BGT has a four way diagonal bubble attack, so good for getting in corners & for spreading jam. Also you can swap it with any candy so allows you to move color bomb without it exploding. The only character I could complete Level 1559 with so good times
@Simon888 Good point about swapping position with other boosters. That would come in handy sometimes. My only complaint is that crossing the bubblegum with other boosters does not create combo for extra power.
