Probably your best bet is `Puppet:GetBoundingBoxSize()`. This function returns a vector with the sizes of the puppet's collision, notable in this case because the Harpy's collision does change size going between flying and standing. You can check the individual axis values by affixing `.x`, `.y`, or `.z` to the resulting variable.

Thank you for you answer.
So does its bounding box actually changes after landing? I guessed so, but finaly i have a conformation.
Thankfully at least one easy solution here in the world of workarounds.

The only thing left is to find reliable a way to make it land to get values.

Thank you again!

The Harpy has an `AirToGround` behavior state that'll make it land immediately; You can set that as the `State` on a puppet entity.

I will try this. Thank you!

Thank you! It Worked. I just swaped Dafault and AirToGround,
