Scooper

Scoopers are harmless little monsters roaming in Soul Sand patches. They are a great source of food provided that you can catch up to them.

Spawning
The Scoopers will replace Zombie Pigmen on Soul Sand. You can learn more about how Zombie Pigmen spawn here.

You can also summon a Scooper using this command: /function imm:summon/imm/scooper. You can obtain a Scooper Spawn Frame with this command: /function imm:spawn_frame/imm/scooper. Make sure to replace the 'imm' portion with whatever version you're playing on if your version is older than Snapshot 3C (example: Snapshot 2A = imm2a).

Behavior
Scoopers idle around unless they've been attacked. In which case, it will run around in panic. They will follow players holding Carrots on Sticks and Beetroots, despite Beetroots being harmful for them.

Breeding
The Scoopers can be bred similarly to Overworld passive mobs. They will accept Poisonous Potatoes or Flaming Tarantula Chelicera. You cannot, however, use it to force the offspring to grow up. Feeding them will also restore their health, but just like with breeding requires a cooldown before they can be healed with food again.

Trying to feed them Beetroot will result in the mob taking damage and eventually dying.

Riding
Like with a Pig, Scoopers can be ridden using a Saddle and a Carrot on a Stick. You can learn more about how Pigs can be ridden here.

Scoopers are, however, much faster than a Pig.

Drops
Adult Scoopers can drop:
 * 1-2 Scooper Meat
 * 1-3 experience

Metahistory
In the unreleased command block version of "More Mobs" for 1.12 there was a Zombie Pig mob. It spawned on Soul Sand and was aggressive, however very short-sighted. It dropped Rotten Flesh. Later on this mob transformed into the Scooper. Scoopers are passive, very fast, and drop better food. Being a food source for the Nether and spawning on Soul Sand was kept, but the mob transformed into something more complex and useful. And less douchey.

Known issues

 * 1) Scoopers panic while being on fire despite being fire resistant;
 * 2) Scoopers have a weird hitbox.
