Perfect day?
Ozwald: for him, it would be a calm and relaxing day, working on his latest sewing project or just going to the mall with his friends.
Higen: going for a big hike to the woods, helping as many people as he can everything leading to a big dinner at his favorite place... his kitchen where Ozwald cooks.
Birthday?
Ozwald: there's actually a chapter about this topic, in "For Thou Happyness!" You can read Ozwald´s favorite birthday unfolds.
Higen: like with Ozwald there might be something similar in the works for the future.
