that's wild. I find that my.... 27-month old daughter (heh, what a coincidence) also recognises the titles of bluey episodes pretty easy..

we can be scrolling a list of bluey episodes, and she knows what they are by the words.. "what episode do you want to watch?" "curry quest!" - sure enough, that's what it's called and that's what the title is

all of the pictures are some form of the characters doing something, so i find them fairly indistinguishable... I haven't tried letting her pick one without the picture, which will be the real test i guess.
