When asriel got the door there stood two a one year old boy and girl in a basket with a 2 month old baby boy . The girl and boys had light blue hair with golden yellow tips. The one year olds right eyes were black the the left one was blue asriel could not see the two month old clods eyes because they were closed."asriel who is at the door" Toriel said as she looked over asriels shoulder *gasp* toriel gasped looking at the three children. They all had a blue and black scarf around a cretain part of there body the little girl had her's around her neck the little boy had his scarf around his waist and baby boy had his on his right arm. "My child please call your father and brother right away" as asriel told his father and brother Toriel took the children inside the house . In the basket was a note that says
'Dear dreemurr family I have heard that you are a very lovely family. The little girls name is blue and her twin aleck and there baby brother coco they need a home so please take them in I have to hurry before they find me but please take good care of them by the way blue has powers and may need training with her brothers
