Grow

The Grow (ビッグ) is Monitor power-up, that appears in Knuckles' Chaotix and is opposite to the Shrink power-up. Monitors that have the power-up, show flat and blue upward pointing arrow icon on the screen. While giving the ability to grow bigger, it also increases speed and jumping ability.

Description
Depending who picks up the monitor power-up, only has the ability for certain amount of time, while the second character remains normal. After picking it up, the character suddenly grows up twice bigger than his normal size. During this, the arrow icon can be seen at the down right corner showing how long the ability takes.

When the character has grow up his size, his speed and jumping weight has increased as well. However it can also make the character more easier to get hit by enemies. The power-up's length takes 20 seconds which after that, the character will return his regular size.
