Block

Blocks are the common feature in the Yeah Jam Fury series that makes up the floor, walls, and ceilings on levels for the three playable characters, Yeah, Jam, and Fury, to interact with. Blocks are square in shape and small in size, and each is depicted with a solid color and a face, both of which vary between types of blocks. Each block has different properties, but each block can be stood on and cannot be passed through by the playable characters.

Types of blocks
There are three types of blocks across both games in the series, with Yeah Jam Fury containing two and its follow-up Yeah Jam Fury: U, Me, Everybody! containing all three. It should be noted that the type of level they appear in affects their appearance.

Yellow Block
Yellow Blocks are yellow in color and are most often seen with wide smiles. They also look in the direction of the played character when he stands atop them, to the side of them, or when falling off of the level, and they tremble when Fury walks. Their unique trait in most levels is Yeah's ability to store a finite number of them in a quota, which he can then place in a nearby empty location. Once placed, they can then be destroyed by Fury's punch or falling weight to be added to the quota. Additionally, the walls of these blocks can be climbed and boosted off of by Jam.

Lead Block
Lead Blocks are gray in color and have angry faces that almost never change. Their main unique trait is their complete indestructibility, making them common in levels with many platforms or walls. Another unique trait is their ability to store checkpoints: if the character falls off of a level, they will refoot on the most recent Lead Block that he stood on. In Yeah Jam Fury: U, Me, Everybody!, this is indicated by a more scrunched angry face on the block. Like with Yellow Blocks, the walls of these blocks can be climbed and boosted off of by Jam.

Ice Block
Ice Blocks are introduced in Yeah Jam Fury: U, Me, Everybody! and are bright blue in color with slight transparency, and the faces are always shivering and exhaling visible air. Their main unique trait is their lack of traction, as they cause the character to slide when walking (with the exception of Fury). The walls also cannot be climbed or boosted off of by Jam, though he can still boost when standing. Like Yellow Blocks, they can also be destroyed by Fury.

Certain B-side levels incorporate Ice Blocks into Yeah's quota, replacing Yellow Blocks in what blocks he can place. However, these Ice Blocks cannot refill the quota once destroyed, as this function is still exclusive to Yellow Blocks.
