Toy jealousy issue, you make the call?

You have a young single mother who has 3 young children by 3 different fathers, there are toys she, the aunts and such buy the kids then there are toys each child’s father buys them (or not). The 9yr’s father buys him some real cool and expensive toys and such for Christmas and the 7.5yr old girl only gets one gift from dad that should have been pretty cool but she thought lame compared to what her older brother got. If she sneaked away after dinner and went and broke all her older brother’s cool toys from his dad what should be done with her and/or her toys to square things up or make it right? Should the boy’s dad be told? If he is not told but found out which will happen eventually would it seem the mother is somehow cares little about his involvement on what goes on?
