The 'Hide-N-Seek' Quest

Lets talk about the new quest that recently came out.

By the courthouse in the middle of the backyard is a bush that will hand out quests asking you to find a 'friend' that is hiding. The quest will be the same regardless if you are a plant or zombie, only the hiding spots and variants found will change.

So far, I found around 30 of his 'friends'. Is there an end to this, or is this simply just a repeatable quest? - a quest to show that this bush is friends with everyone in the planet..
