Prison Capsule

The Prison Capsule, also referred to as the Goal Capsule, is an object that appears in the Sonic the Hedgehog series. It is a large variant of the Wisp Capsule created by Dr. Eggman that mark the goal of the playable Acts, and destroying them is the key to finishing their Acts.

Description
The Prison Capsules consist primarily of two vertical glass tubes. These tubes each stand on red feet and have red caps on their tops with a turquoise spike adorning each of these caps' apex. Inside the tubes is a transparent form of liquid energy with White Wisps floating around in it. Connecting the bottom of these two tubes is a red box with a glowing yellow mark that resembles a half-closed eye on it. Also, arranged on the ground in front of the tubes are four red cones, each with a turquoise spike on their top. Also worth noting is that two of the cones on the ground are taller than the two others.

Overview
The Prison Capsules only appears in the Wii and Nintendo DS version of Sonic Colors. In gameplay, they appear at the end of the playable Act, where they indicate that the player has reached the end of the level. To finish the Act the player is in, the player has to destroy the Prison Capsule. This is best done with either the Boost or the Homing Attack, the latter of which can lock onto Prison Capsules. When the Prison Capsule is destroyed, a multitude of White Wisps will emerge from the Prison Capsule and fly away. In addition, on the Wii version of the game, when breaking the Prison Capsule, the game slows down, thus allowing the player to witness the Wisps' liberation in slowmotion. A few sections later, the playthrough of the Acts ends and the player is taken to the result screen where their performance is ranked.

The Prison Capsules only appear in a few select Acts. On the Wii version, they appear in Tropical Resort Act 1 and 2, Sweet Mountain Act 1, and Aquarium Park Act 4, and on the Nintendo DS version, they appear in Tropical Resort Act 2, Sweet Mountain Act 1 and 2, Starlight Carnival Act 1 and 2, Planet Wisp Act 1 and 2, Aquarium Park Act 1 and 2, and Asteroid Coaster Act 1 and 2.
