1.) Come join our song,
it won't take long,
it's time to learn and play!
He's happy and pink,
and gives you a wink,
he's Morris Think-a-saur-us!

We'll sing and run,
and have lots of fun,
while learning to share today;
join Zerky and Russ,
and all of us,
and Morris Think-a-saur-us!
1.) In Big Fred, Tyler's eight-year-old sister loves to watch Morris Thinkasaurus during breakfast.
