Platform(s): Windows PC, I don't remember what year but I believe it was post 95.

Genre: Children's educational game

Estimated year of release: I'm guessing 90s-2000s.

Graphics/art style: Animated

Notable characters: The main character was a bipedal pig (or something that looked similar) There were also notable characters for each game like the Human Body game had a talking tongue and a pair of ears, one of which had balance issues.

Notable gameplay mechanics: It was one of those games where you had to answer questions to advance in the story, which was different for each game. You could only get three questions wrong before the game would be over and you had to start at the beginning.

Other details: I don't care which of the games you can name because at least knowing the name of the main character would give me the other ones, so I'm hoping describing all the ones I had will jog someone's memory.

One was the human body, and the main character (who was a bipedal pig or looked very much like one) had to travel around and help various parts of the human body and answer questions. One of the first ones he met was a talking tongue who would usually ask questions about taste buds. Then he would meet a pair of ears, one of which couldn't walk without falling down, and you had to say which area of the ear correlated with balance. Eventually you would wind up answering questions about red and white blood cells, etc.

The second game in the series was Plants and Animals, and you had to go on a journey to a farm in order to pick up plants to save your family's farm, where all the crops were dying. Along the way, you had to answer questions about plants and animals in order to get past the creatures who were blocking you. I remember a grasshopper/cricket being in the game, as well as a boar.

The third one I had was something along the lines of "Back to the Future" for the title. It was focused more on technology and it had questions like why manhole covers were round and what shape roads were. I don't remember the overarching plot of that one, besides I think he wound up in a time machine or spaceship and had to figure out how to get home.

The main character's name was always in the title, along with whatever it was focused on, so it would be things like "X goes Back to the Future" or "X explores the human body", I think.
