Better NPC
If you find Minecraft Pocket Edition a bit dull, you can populate it with a plethora of non-playable characters. Simply utilize the Better NPC modification.

In total, the Better NPC modification will introduce over two hundred non-playable characters into Minecraft PE.
To spawn an NPC, switch to creative mode in MCPE and use a spawn egg. Alternatively, you can type /summon rio:npc_cute in the console.
To remove a spawned NPC, enter /kill @e[type=rio:npc cute].

With the mod, you can enhance any map and even create quests in MCBE. Enjoy your gaming experience!
