[s-] Spongebob is in the [4] bathroom of the [-_] house. In front of him is a strange old sponge with a 口 mouth attached to it that is on the tile 一 ground. It wears a cape and tells Spongebob that Spongebob is his 嗣 heir. Unfortunately, all the weird 口 mouth owns is a single 冊 booklet that he hands to Spongebob. Spongebob, who did not know he was 嗣 heir to anything, is nevertheless deeply grateful. Even if all he got was a 冊 booklet about how to clean the house bathroom.
