The Lollipop Sisters are 3 collies who are the cousins of Penelope's cousin.
In a litter of 4 puppies, 3 girls and a little boy runt were born: Strawberry Swirlie, Berry Twist, Rainbow Whirly, and Baby Bottle.
In their weeks/months old age, the 3 sisters focused a lot on their dream of being cooking pups. However, Rainbow Whirly was not allowed to help in the kitchen since her sisters think that she is too small to help. Rainbow Whirly then decided to practice making desserts and found a great gift by making healthy foods into yummy desserts without artificial flavors, corn syrup, and a lot of sugar (but she always adds a little sugar and sometimes Splenda).
