Max and Phoebe track down their aunt for their mom’s birthday only to find out that the sisters have been fighting for years.  Meanwhile, Billy, Nora and Chloe try to replace Barb’s birthday cake.

This time it’s Barb’s birthday and Max and Phoebe are trying to decide what to get Barb for a gift.  This comes the day after Phoebe skipped Max’s band’s performance to have an ice skating party (well, either she didn’t show up or she pre-empted the performance).

Meanwhile, Hank has ordered a chocolate munch cake from a celebrity baker.  Chloe five finger swipes the frosting under Billy and Nora’s supervision and the cake now needs to be replaced.  They decide to teleport to the bakery to get a new cake.

Max and Phoebe soon discover that Barb’s sister Mandy is living in Metroburg, owner of a shop called “Gobs of Globes.”  Mandy readily agrees to attend Barb’s birthday dinner.  However, when she arrives, Mandy states that “I’ll make this your worst nightmare ever.”

Mandy exacts her vengeance on Barb by pretty much destroying the house.  Apparently the source of the animosity is that Barb skipped a performance of the Electric McBooger Sisters.  Naturally, Barb has to have a weird maiden name.

Hank, Barb, Phoebe and Max end up trapped in his lair (where Dr. Colosso is training a new waitress Ruby at his casino – that features a game called Slapjack).  Max articulates that perhaps Mandy is mad because Barb’s missing their performance hurt deeply – in the same way that Phoebe missing Max’s performance hurt Max deeply.  Barb finally apologies to Mandy about missing the performance and all is happy in Thunderville.

Meanwhile, Billy, Nora and Chloe are at the bakery owned by Deena Dessert Diva, who makes Twine videos about turning people in dessert dummies. The replacement cake costs $100 – but the threesome have no $.  Deena offers to give them the cake for free if Billy and Nora serve as dessert dummies.  Nora says no and they teleport back home to get the money.  They aren’t successful and return to Deena’s bakery, called “Bake Me Home Tonight.”  (Got to love the cutesy names)

When they return, they find that the deal has expired and that Deena wants to turn Chloe into a dessert dummy.  Nora offers to pull the slingshot (wink, wink) instead.  She pulls it and aims it right at Deena.  Billy grabs the cake and the three teleport back home.

In the end, Phoebe has gotten Max’s band together for a performance in the driveway.  Gideon’s winner line: “Another year hotter Barb.”  Max is deeply moved and Barb makes up with Mandy by finally saying she is sorry and by performing with her.  Its a weird scene for sure.  When she’s done dancing, Barb is dizzy, and topples into the chocolate munch cake, causing it to crash to the floor.  All that effort for naught!
