- “Hit the bottom of the Egg Block to get all the eggs Yoshi can carry.”
- —Message Block, Yoshi's Story
The spots on Egg Blocks are commonly green, but in Yoshi's Story, they are the color of the current Yoshi (in the Japanese version, the color is always green) and have a light swaying animation. When a Yoshi hits an Egg Block from the bottom, a Yoshi's egg is dispensed, provided he has space to carry more eggs. If the Yoshi is already holding six eggs, no more eggs are dispensed. Aside from green-spotted Egg Blocks, in the Yoshi's Island series, there are also Yellow, Red, and Flashing Egg Blocks, which, when hit, turn into a single Yellow Egg, Red Egg, or Flashing Egg, respectively.
In Yoshi's New Island, two new Egg Block varieties are introduced. One of them releases Mega Eggdozers, while the other one releases Metal Eggdozers. Both of them are four times bigger than a normal Egg Block (looking like green Expansion Blocks). The earlier variety is white, while the latter is black.
In Yoshi's Woolly World and Poochy & Yoshi's Woolly World, Egg Blocks are replaced by similarly designed objects known as Yarn Baskets, matching the game's aesthetics. Instead of Yoshi eggs, they release yarn balls, the game's equivalent to Yoshi eggs. Occasionally, they release bigger yarn balls for the Yoshis to use. Yarn Baskets can be hit from the bottom to release one yarn ball at a time or hit with a yarn ball from any side to release multiple at once.
In most games, hitting an Egg Block from a certain side pushes eggs out in the opposite direction. However, in Yoshi's Crafted World, the direction in which eggs are dispensed depends on the direction that Yoshi is facing. These blocks additionally can be stood upon.
Super Mario series
Although Egg Blocks do not appear in Super Mario 64 DS, if Yoshi swallows a Crate, the egg he creates will be in the shape of a cube, just like Egg Blocks. In Super Mario Sunshine, Egg Blocks (localized as spotted blocks and spotted boxes) appear as platforms in the secret courses of Pinna Park. Most have green spots, but there are some that have magenta, blue, and black ones.
Sonic Lost World
In the Wii U version of Sonic Lost World, Egg Blocks appear in the DLC stage "Yoshi's Island Zone," where Sonic must save Yoshis inside Yoshi eggs and bring them to the goal at the end of the level. Only three Yoshi eggs come out regardless of how many eggs are currently following Sonic.
