Bubble is a soap bubble who is usually kindhearted, carefree and happy, but when she is afraid of something, she will try and prevent it from happening, which occasionally has consequences. Bubble replaces some vowels with "oi" sounds in words, giving her a unique accent. When pushed enough, Bubble isn't afraid of speaking her mind to other characters. She might easily pop, but Bubble is still joyful and carefree. She loves saying “Yoylecake” since it’s her catchphrase. She is a female.
