Monster Life reactions

I've finished the trash can quest. Is that the final story quest? Meh, that storyline ended unexpectedly.

Edit: Apparently not. I failed to read. Seems like I need to level up.

But anyway, Monster Life is more fun than MapleStory. I just wish it didn't lag so much. I accidentally released a rank B monster, despite selecting a rank C monster, because I hovered my mouse over the former after clicking the release monster button for the latter...

This is true. What matters is not which monster you right click, but which monster you hover your mouse over last. It's also noteworthy that you can't release monsters from your barn.
