A relatively easy knowledge (Planes) check identifies the bird-thing as a vrock. A somewhat harder one identifies it as pseudonatural. Knowledge Dungeoneering might identify the starfish creature as a Shrieking Terror.
Except for a few minutes each day when she's renewing her bindings, Yalla has 100' telepathy and
Mindsight active, and is watching for the appearance of anything that isn't mindless. Right now, she's checking for signs of any intelligences, especially in the area Mahmoud has just come from.
