This week Poptropica released four new knight costumes in the Poptropica Store. Two are for girls and two are for boys. Girls can choose between a new Astro Knight costume, the Heart Astro Knight and a Dark Knight costume. Boys also have a Dark Knight costume, and can get a Earth Astro Knight outfit.
The Heart Astro Knight outfit shoots out a stream of pink hearts wherever you go. The Earth Astro Knight outfit leaves behind a trail of, well, leaves. All four costumes let you raise and lower your helmet lid by pressing the space bar. The costumes each cost 75 credits as usual and paid Poptropica members can get them for free.
