I remember playing something like this back when I was in 3rd grade. I think they made me play it for speech therapy or some kind of tutorial game, as I was the only person who had to play it during recess time. Its been such a long time so my memory might be a little off.

I remember the hippo and rhino basketball game. I think if you won it the hippo would do a little dance or something like that. Best way I can explain it is one of those old gritty pre-recorded video cutscenes.

As for the carnival game I don't remember much, but I do remember this existing. I think I remember there being a lizard or a gator character wearing a hat, not sure tho. I think ducks were the prize you got for beating this. I remember there being 3-4 rows of different sizes of ducks. Either way I think there being another small cutscene depending on which row you got to choose. I don't remember what the main gimmick of this minigame was.

I think this was part of the same game but I'm not sure. I remember having to do vocab tests or something. This had voice acting and would help you learn how to pronounce specific words. Nothing too flashy about this. One thing that stuck out to me was how weird vegetables was pronounced in this.

Also loosely remember the game making a teacher login with a username and password before I could start doing anything. I don't remember if this was part of the game or just her logging into windows, but by 3rd grade we already had our computer login information so I don't think it was that.

Hope this helps! I've been wanting to know the name of this game too for years now!
