Billy, Mandy, and The Grim

Billy and Mandy are such spoiled brats throughout the whole entire series of the Grim adventures of Billy and Mandy. And to some extent I see similarities with this show and the Fairly Odd Parents only except Cosmo and Wanda Grant Timmy’s wishes and he got them when he needed them the most. While in the Grim Adventures Of Billy and Mandy Billy and Mandy won Grim in a limbo game (all though not a fair way) And he promised if they one he would be there Friend/Slave forever.
