Here are the group's sidekicks: Tick's capybara Speak, Stanley's dog Milo (please disregard the fact that Stanley is in that picture...he's such an egomaniac), and Link's fairy Navi (not pictured here...just imagine a glowing, obnoxious ball with wings).
Speak was given his name because after Tick had taken a big fall in South America, he imagined that Speak was talking to him (with a British accent, no less). Tick took him home to live in Arthur's apartment with him and to this day imagines he can talk and fight crime by his side.
Milo virtually broke Stanley out of jail, and in doing so saved Stanley's girlfriend, Tina's, life. Milo got nothing out of this except praise from Stanley (he wanted the girl). For a good time, Milo goes cruising for terrier chicks, pees on gangsters and tears Link to shreds.
Navi joined Link when he was a boy beginning his quest. Shouting out helpful hints such as "Hey!" and "Listen!", she tried her best but eventually led to his downfall. She then helped him serve fries at McDonalds for a year before they met the Squad. It is rumored she helps him pick out his outfits.
