Looking for an very old half animated movie and the only real thing I can remember is there was an animated platypus in it with a few other animated animals...

Possibly Dot and the Bunny (http://www.imdb.com/title/tt0087170/) or Dot and the Kangaroo (http://www.imdb.com/title/tt0274470/)

Yep that was it! Thank you sooooo much!

It's actually Dot and the Kangaroo!! Thank you sooooooooooooo much!!

You're very welcome :)
