Having a kind recognized

Hi again.

Thank you to everyone for the help with my Christmas game. it went over well and functioned as expected.

I’ve got a kind, specifically:

a plant is a kind of thing.

an avocado is a plant.

a cactus is a plant.

But when I am in a location with those two plants and I say, deliberately vaguely, “examine plant” the response is that it can’t see any such thing.

Perhaps my expectations are unrealistic but expected it to say which plant or something.

Is this correct, or have I done something wrong?

Understand "plant" as a plant.

That’s funny.

Thank you.
