Other than that, the worlds too, will also carry a whole lot more stuff within compared to the past. Expect to see the addition of caves (will there be a Batcave?), plenty of new flowers, new biomes (such as mesas, jungles, swamps and extreme hills), not to mention abandoned mineshafts, villages, and other places that are worth exploring to sap away your time in the real world from exploring actual lakes and caves around you. New beings, too, will inhabit the various digital nooks and crannies within, ranging from wolves to endermen, and Mooshrooms.
Needless to say, new blocks are also part of the mix, such as Monster Eggs and massive mushroom blocks. Mojang has also thrown in a new “interaction” button that ought to prevent one from punching something by accident, and this update for Minecraft Pocket Edition is available on Android and iOS platforms.
