It looks like Zecora will be joining Derpy at Comic Con. The Toys R' Us booth will be showcasing her as one of their exclusives for later in the year, so fortunately for us, she won't be limited quantity!
Check out this snippet from the press release:
MY LITTLE PONY collectors can corral ZECORA from the EVERFREE FOREST! This glow-in-the-dark version of the fan-favorite rhyming zebra can’t wait to share her magic and sage advice with all of her new friends. ZECORA is available as a sneak peek at Comic-Con International in San Diego for $10. For those not able to visit the show, ZECORA will trot into Toys“R”Us stores nationwide this fall.They forgot to mention that she is probably the coolest looking brushable so far! Mainly because you don't have to brush her.
