Lolo is one of the twin bear sisters, distinguished by her yellow fur in contrast to her orange twin Lulu. Both share a deep affection for their grandmother’s homemade cookies.

Daily tasks and challenges form a core part of Lolo and Lulu's routine. While these activities may seem simple to adults, they represent significant and often difficult missions for the young bears. Their approach involves gathering numerous items in advance, showcasing thorough preparation despite uncertainty about what will actually be required.

Lolo displays emotional responsiveness, with both sisters prone to quick tears that reflect their youthful vulnerability. Yet they consistently demonstrate diligence and effort, persistently trying their best even after failures or becoming overwhelmed during tasks.

The character originates from the "Kuma no Gakkō" picture books, which inspired a 2010 anime film adaptation.
