Over the summer, Dorit Kemsley and her husband, Paul "PK" Kemsley, put their home in Beverly Hills on the market and purchased a $6.475 million mansion with .36 acres of land in Encino, the San Fernando Valley town where The Real Housewives of Beverly Hills pal Kyle Richards and her husband, Mauricio Umansky, have their own $8.2 million home. 

The new neighbors, who have been spending a lot of time together exploring the area, met up for Halloween. Kyle and Mauricio joined Dorit and the little ones for some trick-or-treating before heading to RHOBH alum Adrienne Maloof's extravagant party (which had  a "dinner party from Hell" theme!). 

Dorit's children, Phoenix and Jagger, dressed up like little Ghostbusters (from the hit 1984 film, which was remade in 2016) and they couldn't have been cuter.

Kyle filmed a little bit of the trick-or-treating festivities and posted some clips to her Instagram Stories. It appears that Mauricio went as... Mauricio for Halloween. Even though he didn't put on any kind of costume, that didn't stop Mauricio from taking Phoenix and Jagger by their hands and walking them right up to people's front doors — even the ones that happened to be smeared with blood. What could go wrong?

Mauricio is wearing a Superdad costume, it's just invisible.

It's great to see these new neighbors enjoying their time together and making fun memories.
