Wishbones (The Grim Adventures of Billy & Mandy)

"Wishbones" is the thirteenth episode in the third season of The Grim Adventures of Billy & Mandy.

Plot
After Grim's robe comes out of the washing machine, Billy and Mandy find Thromnambular, a talking skull with ruby eyes and a number nine imprinted on his forehead. Grim tells them that the skull is a magical artefact imprisoned on Earth that must grant his 9 wishes to be free. When Mandy asks Grim why he has not used any of the wishes, Grim tells her that the skull will corrupt the wishes and end up affecting the wisher. Despite this, Billy runs away with the skull and makes the first wish - 1: He wishes to be in an adventure (which parodies Indiana Jones and Jonny Quest), this backfires because Irwin is eaten, which Billy complains about getting him in trouble.

Why It's a Wish Come True

 * 1) Some funny moments, such as Billy thinking that the washing machine is the television and that a show is on, along with him mistaking Thromnambular, a magical skull as a football helmet, Harold's quote "You just bite yourself a week of no TV with that comment, mister", and so much more!
 * 2) Some fourth-wall breaks as well, like when Thromnambular said when before the commercials started, "4 wishes down, 5 more to go. Let's watch some commercials and get back to the show!"
 * 3) The plot is very impressive and creative here, as it has Grim discovering a magical skill called Thromnambular when taking out his robe and he describes it as a magical artefact that requires 9 wishes to be free.
 * 4) Speaking of which, some of the wishes everyone makes (except for Harold's, Pud'n's & Sperg's) are very cool and interesting, with the first one having Billy and Irwin in Jonny Quest & Indiana Jones' suits respectively, and his wish being a parody of the Indiana Jones movies, Harold going back to school (despite being mean-spirited), General Skarr getting a giant statue in his garden to the point where it reaches outer space, Irwin being in a hip-hop music video and having Mandy, Pud'n getting a pet bunny that's actually a monster, Sperg becoming a lady to get into their bathroom, Mindy literally becoming a star in space and Grim wishing that Billy and Mandy never found the skull in his robe.
 * 5) Good Moral: As Thromnambular said to Billy and Mandy said to Irwin, be careful what you wish for.
 * 6) Decent Ending: As mentioned above, Grim wishes that Billy and Mandy never met the skull, and it cuts to the start again with Billy watching the washing machine and Mandy asks if he wants to be a television star, and puts him in the washing machine, much to his delight.
 * 7) Thanks to the first 6 reasons mentioned above, it was a great send-off to the third season.

Bad Qualities

 * 1) The only gross-out bit was when Irwin farted in his swimming pool, and not only Mandy was there, but it made her uncomfortable.
 * 2) Some of the wishes were pretty mean-spirited, such as Harold's where he wanted to be back in high school but kept getting thrown into trash cans, Pud'n's pet bunny actually being monster and so, he gets tortured right until the next wish is shown, and Sperg getting laughed at and picked on by the ladies when wanting to become a lady himself. (Though, Sperg kind of deserved it for bullying Nergal Jr right before).
 * 3) * Nergal Jr's "wish" didn't even qualify as one, as he just wished that he knew what he wanted to wish and then, Thromnambular disappears and he gets bullied by Sperg.

Reception

 * It holds a rating of 8.7 out of 100 on IMDB.
