Pic 2: Homestead Candytree event. Just like the one before, you feed the tree candy dye things, and it gives you exp. Later on, rewards include firework kit, dyes, heart sword, red panda pet, and belisha support puppet (you know, the girl from Halloween event) 3/6 - 3/30
Pic 3: This one's called "spirit water" event. Basically you fight with monsters from Mon-Fri, and you can collect "spirit water". On Sat-Sun, you'll be rewarded with exp based on how much "spirit water" you collected.
