SMB3 Flame Chomp (New!)
A Chomp-like enemy that chase you and fire the fireball at you periodically.
If it's tail reached 0, then it explodes like a Bob-omb.
Tail length can be customized per-NPC in the Editor.

I'm not completely sure if its tail should have an hitbox or not. From both sources that I've seen, the tail hitboxes were absent.

SMB3 Fire Nipper (New!)
A special Nipper Plant that can be found in the World 7-8 of the original game.
It shoot fireball projectile periodically.

Attack length and time can be customized per-NPC in the Editor.

SMB3 Brown Paragoomba
A Paragoomba that flies up and drops Micro-Goomba at you.
The micro-goomba will prevent you from being able to jump until certain time passed then you can shake them off.
You can also shake them off instantly if you go into the water or collect Starman.

SMB3 Upside Down Buzzy Beetle & Spiny
A Buzzy Beetle and Spiny that climbs on ceiling and drops down onto you when approached.
Special thanks for Enjl for Polflip Ceiling detection code, and Yoshi021 and MrDoubleA for shell interaction code.
Do note that it doesn't work with the ceiling slopes though, please use with caution.

YI Wild Piranha Plant & Wild Ptooie Plant
A piranha plant variant from SMW2:YI that tries to chomp you or splitting projectile at you.
Wild Piranha Plant took 1 NPC hit or 5 fireballs to defeat, while Wild Ptooie Plant took 3 NPCs hit or 15 fireballs to defeat.
Do note that Wild Ptooie Plant will only face the preset direction, for ease of level mapping and coding.

Each one took 2 NPC slots, with the stalk shared.

SMB3 Pile Driver Micro-Goomba

SMB3 Pipe Muncher
A small Piranha Plant-like enemy that go in and out of the pipe in alternating pattern.
Can be found in World 7-Piranha Plant in the original game.
The starting phase is depending on NPC direction.

YI Goonies Set
Consists of Goonies, Carrier Goonies (A container, you can set NPC for them to hold), Wingless Goonies as well as their Skeleton Counterpart.
Hefty Goonies and Bowling Goonies are also included as well.
I tried to replicate their behavior to be as close as original game as possible, however some inconsistency are abound. I hope it's not too bad.

YI Fat Guy
Should be working mostly similar to how they worked in YI, except that Yoshi cannot make a giant egg upon swallowing it.

YIDS Pointey
A plant from Yoshi Island DS that hides in the ground, then raises up when the player draw near. The stem completely blocks everything. You can only defeat it by either stomping or throw something to hit the head. This one took 2 NPC slots. Height can be set in the editor.
Screenshot:
YI Baron von Zeppelin
A balloon that drops enemies on the player if they get near. It is a container. For Item version where you need to throw something or touch it to obtain the item, set it to Friendly. The balloon color is randomized from the 4 available colors.
It also comes with projectile Needlenose and Missile. You can also use them for Goonies as well without problem.
Screenshot:
YI Pokey
A Cactus that bounce the Needlenose on its head. It's harmless for a while if the Needlenose is destroyed.
Do note that the Needlenose here is different from the one from Baron von Zeppelin.
