Hm. That looks like an error in the game. There are a couple of other monsters that have 5 likes; their list in the game usually shows 4 items (instead of the usual 3) plus the mystery item.

Looking at our pages here in the wiki, I notice that decorations have tables of "who likes this item", but the monsters' pages don't have similar "who likes this monster" tables.
