The initial part of the Hobo Tattoo is obtained from the Tattoo Shop in the Body Modifications section of the Hobo Marketplace for 20 hobo nickels. On subsequent visits, it may be upgraded, up to 18 times. The cost to upgrade increases each time by 20. 20 (initial part) + 40 (1st upgrade) + 60 (2nd upgrade) + .... + 380 (complete tattoo). A complete tattoo costs a total of 3800 hobo nickels.
- If a version of the hobo tattoo is active when upgraded, the upgraded tattoo will not become active until it is re-selected from the tattoo menu.
- The completed tattoo is the alleged hobo symbol for "It is time for hoboes to take over the United States government", listed in John Hodgman's book, The Areas of My Expertise.
