DOS Games Discussion

I'm trying to find a game that I played in the late '90s or early '00s. It was a game for children, possibly an educational one with a purpose to teach English. I played it either on DOS or Windows, the former is more likely. What I remember about the game (my memory of it is hazy, so I might get some details wrong and most of them I'm not completely sure of):

• the main character was a little girl, it's likely that her name was something like Casey;

• she was in a summer camp (?) and lost her pet - a raccoon, I think;

• to find a raccoon you needed to gather a few items (I think three, two of them were a leaf and an acorn);

• you could wander around the area and do some tasks, for example, there was a garden with vegetables, you needed to click the right vegetable when it was named;

• you could build a sandcastle on the beach (as I remember, there was no purpose to that, just something fun to do);

• in the near end of the game you had to get on the boat (I think there were paw prints near it, so it indicated that the pet was on the boat) and go to an island (?) where you needed to go through an apple garden (I remember something like little islands with apple trees on them).

My friend who lent me this game said that the game was named after the main character - Casey, but I couldn't find such a game. I will be very happy if someone would be able to recognize it! Thank you.

Here is a group of games featuring raccoons, maybe it's there: https://www.mobygames.com/game-group/animals-raccoons
