What is "twipsy"

Twipsy was the official Mascot of the EXPO 2000 World's Fair held in Hannover. The character was created by the Spanish designer Javier Mariscal. His draft was selected in 1995 by an international jury out of 17 proposals in total. During the course of the Expo, Twipsy could be acquired on the EXPO area on forms of merchandise, ranging from a stuffed plush toy, to apparel such as on T-shirts, mugs, watches and other souvenirs, in addition to those with the EXPO logo. Apart from that, stamps showing Twipsy were released, and full-sized versions of Twipsy were running around on the EXPO area and advertising for the EXPO in other countries.
