|Neutral Special||Bubble Burp||6-12%||If the Neutral Special is pushed, Bub will spit a green bubble forward dealing 6% when it connects with opponents. However, if the special button is pressed and held, Bub will spit out a slightly larger bubble that when it connects with opponents, they will be trapped inside the bubble and will slowly start floating upwards. They will stop at a certain point, where they will be vulnerable to attack by Bub. Any sort of attack will pop the bubble which will produce food for Bub. The lighter the character, the more they will float up. The more damage the character has, the longer they will stay in the bubble. If the Neutral special query is held too long Bub will start inflating and start floating upwards.|
