It looks like the huge success of the MLP comic has brought on the requirement for additional staff! Amy Mebberson and Heather Nuhfer have been hired on to bust out issues 5-8 and help ease the workload off of Andy and Katie as the comic continues to expand. I guess this little side venture for the MLP license isn't going anywhere anytime soon?
For an example of Heather's writing work, look no further than Fraggle Rock, which she did an interview for a while back, and if you are curious about Amy's artwork, check out her official tumblr. Sadly Hasbro employment rules require her to remove comic artwork from the site, but I'm sure we will see previews of it in the future
Until then, have a parody she drew of the cast of Strawberry Shortcake:
Thanks to Steve for the heads up!
