I tried this a few months ago, it wouldn't do it. I didn't think of asking about it here until I saw a
question of the same sort.
So what would possible be wrong with the phrase? I've tested and know that Kakuna, Rattata, and Rattata Kakuna can be typed in.
EDIT: ok so I just tried Kakuna again, it didn't go.
Because Kakuna Rattata has 'kak' in it.In South Africa it means sh** or feces.Una Rattata is alright and so is normal Rattata.
Source:I saw another question like this.Except that one's about a nickname.
