This is a Canadian show, and it is different from the rest of Disney Junior's output because it is not animated in CGI. The character designs and voices are adorable, but I personally found the show a little dull.
All the main characters have the same personality, that they're cheerful, kind, and helpful. I am begging you, preschool show creators, stop making copy and pasting the same character archetype over and over.
The kazoo music gets annoying after a while, and overall I found the show pretty boring despite its cuteness. But it might be good for young children to watch, and it's a heck of a lot better than Mighty Express, because this show is calm whereas Mighty Express is hyperactive, flashy, and loud.
