Crystal Cathedral is a church in 123 Greeny Phatom made almost entirely out of glass so, according to Kelly, the attendants could look out at "God's wondrous creation". Most Greenytoon characters attend. According to the episode The Beanson Gang, it is part of the Association of Welcoming and Affirming Baptists.
The church debuted in Season 21.
As with any Church, the main service to the community is their Sunday Service, which most of the Greenytoons universe's characters attend. However, the church has also been host to a few musical performances (mostly by secular groups).
