"Bubbles," Buttercup growled, gritting her teeth at the blue-eyed girl.
"I wanted the last piece of gum." Buttercup whined tersely. She didn't believe she was being selfish, although she had had more than her fair share of the pack of gum.
"It's the only piece I've gotten ahold of," huffed Bubbles, returning to her crayon drawings.
The green puff's brow twitched, and slowly one of her eyes squinted as she watched the blonde chew in-between humming. She refrained from yelling aloud in frustration and floated closer to Bubbles.
The girl looked up from her scribbles and knit her eyebrows, expecting Buttercup to berate her.
"Butterc-- mmph."
Buttercup's lips silenced her protest and her tongue entered past her mouth and quickly snagged the pre-used gum. She pulled away, chewing and popping triumphantly while Bubbles stared, red and open-mouthed.
Pop!
The sound snapped Bubbles from her shocked humility. Buttercup was blowing a large pink bubble. Bubbles moved her mouth and blinked, realizing what happened.
"Professor! Buttercup stole my gum!"
