To find it, click the links provided by Krawk Lover here until you find a striped negg (not a toy one!) - don't forget to + rep! One has been released as of 20/4/11 - the first striped negg. These count towards the community challenge - if the community can collect 5 million plastic and toy neggs by the end of the festival, everyone who participated will receive a prize. Whilst wandering about Neopia, you might also get plain toy neggs. You can collect them in any order, but getting them on the day they're released will grant you a bonus prize. A new one will be released to be found each day.
Kari is challenging Neopia to find certain plastic Neggs.
