Sonic's Schoolhouse is an educational computer game that teaches young learners mathematics, reading, and spelling, released in 1996 with collaboration of Sega and Orion Pictures Corporation.
In addition, players can earn access to two mini-games (a collect-the-rings game and a match-the-statues game) and a "field trip" section which gives them numerous facts on the various animals in the game (through video clips).
The entire game plays in a similar fashion to id Software's Wolfenstein 3D, in that you play in a world that has no variation in height and is largely composed of right angles. You pick up nearby answers (ranging from bouncing letters and numbers to balloons with various pictures on them) and shoot them back at a blackboard to answer questions (usually filling in the blanks; in the reading section through the yellow door you match up pictures with their words instead), or otherwise recycle (much to Sonic's pleasure, as recycling is good for the environment). If you get all ten answers correct, Sonic holds up two sticks with fireworks on them, saying "You got all ten right! Great job!"
Sonic the Hedgehog himself is not playable, but acts as the guide; instead, you choose from numerous animals to play as. Doctor Robotnik and his Badniks also show up to steal your answer, or in the ring mini-game, to steal all your rings.
The sprites used for Sonic are borrowed from the cancelled Sonic X-Treme.
Sonic is voiced by Meg Inglima (who makes him sound a lot younger), so this marks the first 3D Sonic game to have a voice actor.
In the files of the game, a strange talking clock is present. It is possible that this clock was going to appear in place of Sonic. The voice of this clock is most likely provided by Meg Inglima, Sonic's voice actor for this game.
In some versions of the PC box artwork (the second version on this page), Sonic's arms, which are colored peach, are actually miscolored blue.
