The Pogo Spring, also known as the Hop Spring (ホッピング Hoppingu?, lit. "Hopping"), is a spring-type power-up that appears in the Sonic the Hedgehog series. They can be obtained from either metallic boxes or monitors. When used, they equip the player with a mobile spring.
Pogo Springs, like normal Springs, propel the player into the air; however, they are utilized in a different manner. Once activated, the Pogo Spring appears beneath the playable character's feet and they will automatically begin bouncing. The player cannot gain momentum while using the Pogo Spring, and will remain at a set speed.
If the player jumps while using the Pogo Spring, they will jump higher than normal, but will also lose the power-up. Taking damage will also cause the player to lose the Pogo Spring, along with their Rings.
The Pogo Spring first appeared in Sonic Chaos, where they can be found in Sleeping Egg Zone and Mecha Green Hill Zone. These springs are set in grey metallic boxes that have a black-and-yellow striped line around. When the player opens the box, the Pogo Spring is set underneath them and they will start constantly bouncing. The player's movement can be controlled with , and they can use / to jump off. Pogo Springs are also necessary to complete the second of the game's Special Stages.
Sonic the Hedgehog Triple Trouble
In Sonic the Hedgehog Triple Trouble, Pogo Springs can be found in Great Turquoise Zone and Meta Junglira Zone. Unlike in Sonic Chaos, Pogo Springs are found as monitor power-ups instead of being set inside metallic boxes. As in Sonic Chaos, the player can control the Pogo Spring with and hop off the Pogo Spring by pressing / once.
Sonic Rivals 2
In Sonic Rivals 2, the fortieth collectible card, which includes the Sonic Chaos artwork from Sonic the Hedgehog The Screen Saver, features Sonic on a Pogo Spring at the forefront. It can be unlocked once the player has completed story mode with all of the characters.
- Pre-dating Sonic Chaos, the Simon Wai prototype of Sonic the Hedgehog 2 has unused sprites of a monitor icon depicting what appears to be a Pogo Spring. It is possible that the idea to use a similar kind of gimmick existed at some point in the game's development.
- The cover artwork for the Sega Game Gear version of Sonic Chaos shows Sonic using a yellow-colored Pogo Spring, whereas the game itself only contains red colored ones.
