I'm neutral (leaning toward support) about the light pink dye but I love the idea of cattails in Minecraft.
But I can't for the life of me figure out why they would be growing out of lily pads?
I personally hope the new Mystery Block replaces the eight Gold Blocks in Ocean Monuments.
And on the subject of Guardians: They seem to be creatures in the vein, and maybe even a reference to, Beholders. Specifically I'm thinking of "Eyes of the Deep". Speaking of which, I'm rather fond of eyeball monsters and I hope we get some more of them in Minecraft 1.9, hopefully some flying or hovering types and not just aquatic ones. Minecraft desperately needs some hostile, FLYING Overworld Mobs.
Bamboo: Bamboos are blocks that are only found in bamboo forests. Breaking 1 of these will give you 3 Bamboo Chutes. Bamboos don't need water to grow. They grow 1 block in 4 minutes, while they do, you can hear it make a cracking sound. Breaking a bamboo will take you 3 seconds with hands, 2 seconds with an axe and 0.5 of a second with a sword. One one question: how tall would bamboo grow? I was thinking anywhere between 10 and 15 blocks high would be about right.Also maybe bamboo should be able to spread slowly like mushrooms do.
Bamboo Chutes: Bamboo Chutes are gotten from breaking bamboo. With these you can craft planks. However, planks need 9 bamboo chutes rather than 4. Bamboo chutes can be replanted, but, unlike sugar cane, you can't stack them up. This is how bamboo chutes look like: Can we make bamboo sticks too? What about a bamboo fence equivalent?
Sakura Leaves: Sakura leaves are the upper part of the sakura tree. Sakura leaves have their own special thing. Sometimes they fall like sand! But they do not remain blocks. They look like snow, and can stack up! When leaves fall, there also is a chance of a cherry falling with it. The cherry appears in the texture. To get the cherry, you right click the patch. I like the intent but not the mechanic. A better implementation would be for Sakura petals to fall during rain and collect on the ground just like fallen snow mechanic. [Another suggestion that uses "Rain = falling leaves" is the Scarlet Forest Biome. Take a look at that suggestion for ideas how to make this work. Also, instead of clicking the cherry, simply breaking the "fallen petal" block (or use a shovel like collecting snow balls) would be simpler.
Red Pandas: Those guys will be found sitting on top of oak trees. They will give 1-2 red wool and 1 black wool. Similar with the panda mechanic, the villagers will not trade with you and iron golems will chase you. These animals are 1 block tall.
Last but not least, Pandas!: Pandas are found in bamboo forests. they are normally sitting, like steve riding a minecart. These guys do not provide meat when killed. They provide 3 black wool and 2 white wool, and, when you kill a panda, villagers will not trade with you, and iron golems in the village will start to chase you, meaning that they will kill you. Breed them with bamboo chutes. These animals are 2 blocks tall.
NOTE: Pandas and red pandas can NOT be tamed.
Yes for Pandas, No for the villager aggro mechanic.
