Get ready for some scares and thrills in Week 7 of "Dancing with the Stars" season 21. The next episodes of the dance competition will be one with the Halloween season but fans should be treated with performances that are by no means dreadful but are scary awesome.

This week, however, will be made specially spooky and thrilling with the remaining couples teaming up for Freestyle Team Dances. The pairs will be divided into two groups – one led by Bindi Irwin and another headed by Nick Carter.

The latter's posse pays homage to the phantom-catching dream team Ghostbusters by naming the group Team Who You Gonna Call? Members are Irwin and Derek Hough, Alexa PenaVega and Mark Ballas, Carlos PenaVega and Witney Carson and Alek Skarlatos and Lindsay Arnold.

The group promises an interesting showing knowing that best friends and solid contenders Ballas and Hough, whose teams in the past "Dancing with the Stars" season never lost, will be performing for the same team. Buddy TV says that overall, this group looks strong.

The second group for the upcoming "Dancing with the Stars" season 21 week is named Team Nightmare plainly because its performance will be tuned to "This is Halloween" from the all time favorite stop motion dark fantasy musical "Nightmare Before Christmas."

In this team, Carter and his partner Sharna Burgess are joined by Tamar Braxton and Val Chmerkovskiy, Andy Grammer and Allison Holker and Hayes Grier and Emma Slater. As per Buddy TV, the team sets Grier apart in terms of age.

Apart from these exciting team performances, there will also be individual routines to be performed by the contestants. Of course, after all the dancing festivities, another couple will have to pack their bags and head home.

"Dancing with the Stars" season 21 Week 7 airs Oct. 26 at 8 p.m. ET and Oct. 27 at 9 p.m. ET on ABC.
