Retreatle Enemy Update!

Retreatle

[p]The new Beetle Enemy is here: Retreatle! Is it a feature or a bug? (I stole that joke from our Lead Composer). [/p]
[p]The Retreatle is a new enemy with some fun interactions. While its shell is on, it can't be hurt unless you shoot an arrow directly at its open eye, or hit it into a pit. [/p]
[p]The shell can be removed with the Frog Glove, the Retreatle will scamper towards its shell once removed. [/p]
[p]The shell can be pushed and also weigh down floor switches and transparent switches.[/p]
[p]If the shell is pushed into a pit or is far enough away across an obstacle, the Retreatle will... retreat! [/p]
[p]With its shell removed the Retreatle can easily be defeated. [/p]
