While Josh and Tom snigger Olivia explains.

Olivia: What? Oh no no, these aren't parts of my feet. These are my "sandals". There another type of clothes called shoes. Humans wear them on their feet to keep them warm and protect them while walking. This is what human feet really look like.
Olivia then wiggles her toes while Littlefoot and the others stare with interest. Then look up with relieved looks on their faces.


Ducky: Ooooh. *She points to Josh and Tom's feet* "I wondered why Josh, Tom and Meg have no tootsies.
Petrie: Human tootsies very wiggly too.
(Yeah like in my captions in the caption this topic, I thought I'd have Ducky and Petrie refer to toes as tootsies to make it cuter)
Josh: Ah well you see me and Tom's shoes are a type called sneakers, they cover the whole foot, and we also wear these soft whites things called socks with them to make them more comfy. *He says this while pointing to one of his sneakers and the sock poking from the top.*
Tom: And Meg's wearing a onesie, they cover almost the whole body including the feet.
Littlefoot: Well with that out of the way lets starting jumping those stones to get to across this river.
