The Slippies are a group of Hippies that joined the Arkvoodle Cult.
The Slippies wanted to join the Cult of Arkvoodle after hearing the word getting around that Arkvoodle seemed like a groovy god to them. They wished to "sign up" for the cult, so Crypto signed them up. They were glad to have joined, however they said they needed their leader Shama Llama to be rescued. They then told you to ask The Freak where he is because they didn't know.
After you rescue Shama Llama, they are seen as part of the cult.
- They are the only Hippie group that immediately we're with Crypto because they had heard good things about Arkvoodle and the cult.
