HAPPY CONAN SUNDAY! … and Easter. That, too.
But seriously. Imagine for a moment that alien space bunnies (?) celebrated Easter. Now, think about ickle Shinibun/Bunnichi trying to find eggs that Yuusaku Trollsaku hid.
It would probably take him all day long and into the night, missing out on all of the other Easter fun (while Yuusaku and Yukiko enjoy a big, fancy lunch and eat all of the candy in Shin-chan’s basket).
and when he finally finds the last egg…
…it probably has something like “it took you long enough, son” written on the back.
