Super Mario Advance 4: Super Mario Bros. 3/Unused Objects

A large number of objects were created or planned for use in World-e levels, but ultimately went unused. Object IDs will be given where applicable. Unless otherwise noted, replace bytes in the ROM to see the object. This will replace the first Goomba in World 1-1 with the appropriate item.

Test Enemies


Object ID: (generator),  (stationary),  (flying)

What appear to be test enemies, using a blue version of the Warp Whistle graphic.

One type is stationary (but can still hurt the player), while the other chases after Mario/Luigi. When it changes its angle, the sprite rotates as well. You can't see Object ID with the method mentioned earlier.

Bomb


Object ID: 

A simple bomb that will not explode until the player picks it up. Once picked up, the bomb will explode in about 5 seconds.

This will act like a Bob-Omb explosion, destroying nearby enemies and potentially harming the player.

Floating Block


Object ID:  A block that bobs up and down in the air.

Acts like the Chomp Rocks in Super Mario World 2: Yoshi's Island: standing off-center will push it to the left or right and rotate the block. Unlike the Chomp Rocks, this cannot hurt enemies. It makes a splashing sound when it moves, so it might have been meant for a water level.

Number Blocks


'''Object ID:

''To see these blocks, change ROM address to, and ROM address  to. This will replace the second ledge in World 1-1.''

An interesting concept for a block. When these blocks are picked up, the block below will be set to 0 and the block in hand will be decremented. Throwing these blocks will stick them to any solid surface, even walls! They can also be thrown at enemies to kill them.

P-Wing Block


'''Object ID:

''To see this object, change ROM address to. This will replace the second shrub structure in World 1-1.''

An unused block type that gives an unused object! This in-level P-Wing acts just like the map one, though obviously this can't be saved for other levels.

Mushroom Blocks


'''Object ID:

''To see these blocks, change ROM address to, and ROM address  to. This will replace the second ledge in World 1-1.''

Work exactly as expected – they can be picked up, put down, and thrown at enemies to kill them. However, the tile the Mushroom Block is put in front of will be destroyed when picked up. Also, they will not stop pipes from spitting out enemies.

Stopwatch


Object ID: 

Touching this stopwatch will freeze the stage timer for 5 seconds. This would have been handy in areas with short timers.

Dolphins


Object IDs: (Dolphin swarm),  (single vertical Dolphin),  (single horizontal Dolphin)

These Dolphins are ridable and won't harm you. That's pretty much it.

Fireballs


No object IDs found

Yoshi's fireballs, with angry eyes. Since they don't seem to be coded, their purpose is unknown.

Fishbone


Object ID: 

Identical to the Fishbone from Super Mario World, but with a redrawn sprite! Too bad there's no good place to put it.

Giant Gate


Comprised of 3-Up Moons and Cape Feathers, although the Bonus Star graphics remain intact. Hitting the bar will act like hitting the card at the end of a level, minus actually getting a card. Going above the bar will not count as clearing the level.

Lakitu's Cloud


'''Object ID:

This seems to be Lakitu's Cloud vehicle, but the graphics are nowhere to be found in the ROM. It does function, though, and can be moved with the D-Pad, but will never disintegrate.

Land Cheep-Cheep


Object ID: 

A Cheep-Cheep that flops around on the ground. Unlike the harmless Super Mario World variant, this Cheep-Cheep will hurt you if you run into it, though it's still hittable by stomping.

Para-Bomb


Object ID: (X-position must be odd)

Note: This object will not work with the aforementioned method.

While the object with this ID is used, the only place it appears in the e-Reader levels spawns Para-Goombas instead, as the object location's X position is even. The Para-Bomb graphics have been updated to match the Super Mario Bros. 3 Bob-Omb design. When they land, they turn into wind-up Bob-Ombs, and will only explode when you stomp on them.

Porcu-Puffer


Object ID: 

Homes in on the player and stays near the water's surface.

Silver P-Switch


Object ID: 

This switch can be carried around like the Super Mario World switches. Hitting the switch will turn all nearby enemies into silver coins, which can be picked up for points and eventually extra lives. Unlike SMW, this will not play any music.

Swooper


Object ID: 

Stays in place until the player is in close proximity. Then it will move left, do a loop, and then continue moving left indefinitely.

Fuzzy


No object ID found

This would presumably act like the Fuzzies in SMW. No associated object ID has been found, so it's possible that it was never programmed.

Yoshi Egg


No object ID found

Graphics for a Yoshi egg. As there are no other traces of Yoshi in the game, this object's purpose remains a complete mystery.

Arrow Lift


Object ID: 

Identical to the Arrow Lift in Yoshi's Island, this ball will spin constantly until the player jumps on it. Once on board, the ball will move the direction in which the arrow points.

Flutter


Object ID: 

Presumably Wigglers after metamorphosis, these enemies appeared in only one room of Yoshi's Island! When the player stomps on a Flutter, they will become enraged and charge in the direction of Mario/Luigi.

Boo


No object ID found

Presumably would have functioned like a larger Boo Buddy. Strangely enough, this Big Boo graphic resembles its unused graphic from the original Yoshi's Island! The only apparent difference is the palette used.

Veggie Shell


'''Object ID:

''To see this object, change ROM address to. This will replace the first set of bushes in World 1-1. Note that you must have Veggies activated: Use the CodeBreaker code .''

While the shell is technically from Super Mario Bros. 2, this scaled-up version comes from Super Mario Advance. Pulling up the vegetable sprout will give Mario/Luigi this giant shell which will do everything a normal shell does (kill enemies, break bricks, hit blocks), but it's much faster and you can ride on top of it. You can also pick it up after you've thrown it.
