Thrilled 7-year-old gets ultimate Ghostbusters surprise (pictures)

Braeden Rios, 7, sees the Iowa Ghostbusters' ECTO-1 arriving at his home in Clinton, Iowa for his birthday party on Tuesday. Braeden's twin sister Abigail, 7, was also quite surprised to the paranormal investigators and eliminator pulling into their driveway.

Braeden's mother Michelle said she approached the cosplay group on Facebook while trying to find a gift for her son on the Web. She told them about her son's obsession with the Ghostbusters and his struggles with bronchial malacia, a lung disease that can cause breathing problems and respiratory tract infections. Andrew Smith, a co-founding member of the Ghostbusters group, said he and his co-founder Matt Bousman offered to make a personal visit for Braeden's birthday party.

The Iowa Ghostbusters also gave Braeden two vials of ectoplasm including the green kind usually found on Class 4 full roaming vapors and the pink kind that makes toasters dance to Jackie Wilson songs.

Braeden unwraps another special Ghostbusters gift for his seventh birthday.

Braeden jumps with joy at the sight of the new Proton Pack he received from his parents for his birthday.

Smith and Bousman let their new recruit actually fire a beam of protons and hope that he doesn't cross the streams causing all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.
