Hot Air Balloon Hidden Achievement

Someone said the tree needed to show a flower effect, but if your graphics settings are low, you only get a round sparkle and no flowers. Anyway, since I managed to get it, it seems like the round sparkle is enough! The night one is really pretty! It took me a long time to see the deer, but as someone who's done the hide-and-seek achievement... this was easier than the hide-and-seek achievement.
