Hey people. My idea for Minecraft is cold lava. Cold lava would be an orange fluid (not like real cooled lava.) Cold lava would be a special type of water that would spawn in the Nether. This water would be able to spawn in deep lakes in the nether but not very frequently. It also will disappear in the Overworld like normal water does in the Nether. This water would be very dense compared to normal water and it would be as easy to move through as lava. However, it won't harm the player. If cold lava and lava collide, granite would form. However, if normal water and cold lava collide (could only happen in the End) another water would result.
Slime oil would be the result of cold lava and normal water colliding. It is red. (i know that red doesn't come from these two colors but that's not the point.) All of the cold lava and normal water would turn into slime oil. Slime oil is special as it can be in all of the dimensions like the Nether and the End. Slime oil has very interesting properties compared to the other forms of water. Slime oil will be quick to move through by swimming and in boats so it would be better for transport than ordinary water. Also, it would have different things happen when it hits other forms of water than cold lava. When it hits lava, it will form netherrack and when it hits cold lava it would form granite. However, something interesting would happen when it hits normal water.
A synthetic slime (aka red slime) would be a new form of mob that would appear when red and normal water collide. When it forms, all of the water that helped form it will disappear. The synthetic slime would be red with orange eyes. There are many things that differentiate this mob form the magma cube and the normal slime. For instance, this mob would be dealing 1.5x the attack damage as the normal slime. Also, it would travel through groups of two hops at a time and at a higher speed. Another thing is that this mob would only have two forms: the big slime and the small slime. The big slime would spawn four mini slimes when it dies. Each of these mini slimes would drop a synthetic slimeball piece. Three of these in a crafting table form a synthetic slimeball, which does anything that a normal slimeball does as well as forming red variants of block requiring slime. The only exception is that the red slime block would be more bouncy when it is powered by redstone. It is intended as a late-game alternative to a normal slime. However, when the little slimes form, there is a slim chance a special slime will appear.
An orange slime is a special variant of the red baby slime that forms rarely when a big red slime is killed. This slime is neutral as opposed to its brethren. It has an opposite color scheme than its red brothers orange body and red eyes. This slime can be tamed using a bone, but if the taming fails it will turn aggressive for a while (this little slime attacks!) and you must wait to try again. However, when tamed, it is a useful adversary. Its purpose is to fetch items for the player. Whenever the orange slime touches an item on the ground, it sticks to the orange slime. While pointing somewhere, the player can press F to get this slime to go there. The slime will get what is there on its body. Press F again to get it to come back, even if it is not done traveling. This slime is mainly intended for mining trips, as it is immune to lava and can get ore across a gap. However, over time it loses its stickiness and needs to be right clicked with a bucket of red water to maintain it. Also, it can fetch loot from a mob because hostile mobs will pay no attention to it.
Now for some balancing things. I personally don't believe that cold lava needs any balancing things because it can't really be used in the overworld and it doesn't have many uses. Also, it is pretty rare. Maybe in the future it could be used to make some nether crops but I am not going to put anything about that here. However, the red water needs some balancing in my opinion because once people get it, they may start to use it for everything. When you are growing crops, you will only be able to use normal water to grow your crops. However, if you decide to use red water, you will be in for a shock. The next stage the crops grow, they will turn into a new plant called a slime rot. A slime rot is essentially a bunch of rotten leaves. Fully grown plants will not be affected but non full grown plants will. When you try to break a slime rot, a mob form of this spawns in. It is basically a little red slime with a the rotten leaves on top and little legs/roots. It has 5 health points and deals 1 damage in each hit. However, it has a ton of knockback and has a stunning attack with a new stun effect which stuns the player for a second and can only be used every 5 seconds, within which frame either you or it will probably be dead. It drops 0-2 slime spores, which can make things with a stun effect as well a a slimeball. Also, it can rarely drop it's leaves in an unrotten form. When you right click this onto your pet orange slime, it will also become like a slime rot. With these new leaves, it can be used to dig underground 5 blocks (won't break any blocks.) When it surfaces, if it is covered in lava there is lava and if not it is safe to dig. This will help people who just wanna dig straight down.
Thanks for reading. I would like to see your feedback in the replies.
This topic used to be called Orange and Red Water + Orange and Red Slimes but I changed the name.
Thanks for the feedback! I intended for the synthetic slime things to be basically the same as normal slime block as it is just a late-game alternative for people without access to the normal slimes, but the super bouncy idea could be good. I think that it normally could be like a normal slime block, but could be extra bouncy when powered with redstone.
