That is where they built the Kid's Bug Garden during last F&GF (the year before it was between Morocco and France). The description failed to mention if there would be playground equipment again as there was in the last 2 years, which made Epcot and this my daughters favorite place to be at WDW last year.
Did you see anything through the green walls, in particular playground equipment? Last year they had a giant 'spider' web (geosphere) that the kids climbed (after the F&GF it was moved to Conservation Station at AK).
