How are you meant to get blue/purple slime in Tinkers? Congealed Maga Slime blocks are easy in that a visit to the nether and a bit of wandering can yield a magma slime sapling or two, when planted, will generate a congealed maga slime block tree. (in 1.10 at least) both purple and blue saplings grow up into trees that have congealed green slime block trunks. Allowing the entire tree to decay might yield 1 slime ball. Taking buckets of Liquid Blue Slime off the islands doesn't seem to help - slimes don't spawn in liquid slime except on slime island chunks (apparently). So, is making a tool with slime parts the only way?
