There are many packs like it, but this one is mine.

W's Shulker Forretress

W's Shulker Forretress is a faithful adaptation of the Cobblemon mod's shulker Forretress form which was removed in 1.7.0. These readded Shulker Forretress can be obtained in multiple ways:

• natural spawns in End Cities
• evolve a Pineco while holding a Shulker Shell
• give a Forretress a Shulker shell in it's cosmetic slot Naturally spawned Shulker Forretress, on top of their regular counterparts' loot pool, will drop 0-1 Shulker Shells on defeat.

Future updates (no promises)

• Xaero's Minimap compatibility
• Option to revert Shulker Forretress to normal Forretress via cosmetic slot

Important Notes:

This pack needs to be put in both your resource pack and data pack folders to function properly. Since resource packs and data packs do not share pack formatting, the data pack will show up as "Made for an older version of Minecraft" - It will work fine! Thank you to the much smarter people on the Cobblemon Discord who helped me develop this. Credits can be found in credits.txt.
