Minecraft 1.9 Data Tags changed?

Solution 1:

First minor issue is that you have unbalanced quotation marks:

["Place this item in a dispenser and power","to destroy the block infront ]
                                             Need to end the string here ^

As of 1.9, you need to specify data about the entity, including its type, inside of an EntityTag compound tag, like this:

/summon Item ~ ~1 ~ {Item:{id:spawn_egg,Count:32,tag:{EntityTag:{id:"Bat"},display:{Name:"Destruction Pellet",Lore:["Place this item in a dispenser and power","to destroy the block infront"]}}}}

Solution 2:

You need to use the {EntityTag:{id:"Bat"}} they indeed changed that. And btw the damagevalue needs to be 0 for this to work so the command will be /summon Item ~ ~ ~ {Item:{id:"minecraft:spawn_egg",Count:32b,tag:{display:{Name:"Destuction Pellet"},EntityTag:{id:"Bat"}}}c
