|Memorable Quotes||I think you are right, but I think I'm already stuck.|
No, I'm super stuck. I just sank to my neck.
It's pulling me down. I'm up to my chest now. It's covering me just like a blanket.

Hannah Morgan is a major girl from the Second Generation of Barney & Friends, and a major (initially recurring) girl from Rocko Squad Prime.
Hannah has the same outfit from the Barney Home Video called Barney's Night Before Christmas in all of her episode appearances. She also has pajamas, seen when she goes to bed, taken from the same video as her usual outfit. In her first three appearances, Hannah's outfit is nearly unchanged from the aforementioned video; the only difference is that she wears braces.
- Hannah cries for the first time in Rocko Squad Prime during Halt, Hannah. This is also the first episode where Hannah appears with Anna, Kelly, and Samantha. It is revealed in this episode that her Grandma Johannson has died, which is because Crash Gordon killed her.
- Hannah never sinks in sand, which makes her one of the only girls from Barney to have only sank in mud. Starting in Ramona Returns, Hannah owns a Sinkinator which Meteorite found in Ramona and Beezus Quimby's mom and dad's bedroom. She uses it for the first time in Sally Stays.
- Hannah has the loudest snoring of all the children from Barney & Friends, dwarfing the volume of even Natalia's snoring.
- Hannah is the only girl who simply talks with Rock Buddy in both of her sinking episodes during Season 2.
- Hannah is the fourth character to have multiple sinking episodes in one season, the first three were Natalia, Marcia Brady and Gina. She has one sinking episode in Season 1 and at least two sinking episodes in every season after that.
- Hannah is the only girl to simply talk to Rock Buddy while sinking and never explain any of her RockTube adventures.
- Hannah moves into Rocko Base in Ramona Returns, effectively making her the second recurring girl to be promoted to a major girl. The first was Marcia Brady.
- Despite being a famous Barney girl from its second generation, Hannah only interacts with her babysitter in three episodes, particularly Sinky Shulk, Oona's Season 4 sinking episode, and her Season 5 sinking episode, the latter being the only episode where all of a little girl's roommates alongside the little girl who sinks appear in a K. Rool segment.
