The file starts with an int which defines the amount of entries, then each entry has the following layout, being 0x0C bytes long in BFBB and 0x10 in Movie:
'''Battle for Bikini Bottom'''

unsigned int SubObjectBits;

| 0x04 || uint32 || '''SubObjectBits''' || Specifies which RW atomics in the model to apply this pipe info entry to. Each bit is an on/off state for an atomic, starting with the last atomic as the least significant bit (0x1) and ending with the first atomic as the most significant bit.
For example, if a model has 4 atomics:

When a pipe entry should be applied to all atomics, this is usually set to 0xFFFFFFFF.
