In the attached images you can see the Bat and Octane follower on the remote user are highlighted blue as if interactive. Both of these objects use VRCConstraints: the follower has a Position and Rotation constraint and a physbone, and the bat has a single Parent constraint.
These are only visible within the typical interaction range.
(Unsure why the follower is visually that far away but that's a separate issue that may or may not be my fault)
