Costume Guidelines While we encourage creativity, we also value safety and good judgement. Please take a moment to read over our latest rules and regulations: Costumes must be family-friendly and may not be obstructive, offensive, objectionable or violent. Guests who dress like characters may not pose for pictures or sign autographs for other guests. Costumes may not contain any weapons that resemble or could easily be mistaken for an actual weapon. Costumes may not contain sharp objects, pointed objects or materials that may accidentally strike another guest. Large, full-body inflatable costumes are not allowed. Large inflatable costumes can scare our animals. Adults may wear costumes but we ask that they be family-friendly (not gory or scary). This event caters to small children. Adults may NOT wear costume masks that cover the face. The Zoo reserves the right to ask adults to remove costume masks. In addition to the standard Kanga’ Klimb guidelines….No loose-fitting costumes, accessories, or props may be worn on the course. This includes but is not limited to wigs, hats, capes, chains, robes, ect. No costumes that restrict movement or prevent the harnesses from properly fitting. Loose onesies, bulky costumes, or inflatables, are not allowed. Guests who do not adhere to these guidelines may be refused entry into, and/or removed from the zoo unless his or her costume can be modified to meet the above standards.
