If the face paint doesn't give it away, this is Max's favorite dinosaur. He alternates calling him "Long Neck" and "Little Foot" (mostly Little Foot), but waltzed up to my husband the other day and asked for his "Brachiosaurus" (in jumbled toddler language). It took us four or five tries to figure out what he was asking for, but once we figured it out, we looked at each other and said "Where did he learn that?!".
Looks like the educational portion of Dinosaur Train isn't falling on deaf ears!
