...the disembodied head of preacher Robert Tilton

For this trip to the Island of Forgotten Anime, we're going to showcase some religious-themed anime made by Hikyou-Kisei Studios, which were usually international co-productions with various religious institutions around the world.

Bobu Bobu Bobu Hai Hai Hai which... well, I can't quite translate into anything coherent, but it features the adventures of two children, Cash and Penny, who travel around the world accompanied by the disembodied head of preacher Robert Tilton and learn about the importance of giving money (to Robert Tilton) so they can make better use of their prayers to God, or something. I don't get it either.

Here - see if you can tell me what this is all about: The Continent of Lost Anime
