Swarm of Fangs stat block

[Lorewalker]

Is there supposed to be a stat block for swarm of fangs? It came up in a game recently where a GM asked me to provide the stat block when attempting to cast the spell, yet the Monster Codex does not provide one nor can I find one in any other book.

No it doesn't come with a stat block because it is a magical effect that shares some qualities of a swarm. It isn't actually a creature.

Sort of like black tentacles.

If that is true, would it pop invisibility and count as magic for DR, despite also being a summoned swarm? Invisibility

It would seem this spell could use an errata to explain that, despite being a summoned creature, it is an effect similar to flaming sphere and black tentacles OR state that is it an invincible summon OR make it an invincible creation type OR give it a stat block.
