Before Eternal Sugar was sealed with the rest of the Beasts she had created a child for her to love and cherish. Her baby made the Paradise just a little more wonderful.
One fateful mistake changed everything. Eternal Sugar Cookie was just picking some flowers when the toddler wandered off. All she heard was a scream. The toddler had accidentally wandered over the cliff, crumbling as a result.
Eternal Sugar Cookie mourned the loss for months till her sealment. Little did she know that the residue from the souljam would bring back what she once lost.
Thousands of years had passed since then and Eternal Sugar Cookie returned to her Paradise to lure in more Cookies and fulfil their happiness. That's where she finds a familiar small one, alive once more and sitting on the field of flowers.
