What Pokémon’s typing do you always forget?

Was playing through Silver, encountered Suicune and realized that I once again remembered it as an Ice type and not a Water type. This has happened consistently for over 20 years, I just really associate it with Ice moves and also I think its design looks more Ice type. I’m also probably consistently misremembering the trio as having the same types as the Kanto birds.
So I’d love to know if anyone else also have a pokemon or two that they keep misremembering the typing of?
