I intend on giving my group an encounter with the Sarlacc larva field featured in the novel Kenobi...

Based on the scene, the larva should be somewhat mobile, and able to attack... Just not sure what kind of stats to give them.

Any ideas? While they're larva, they're still large enough to capture and eat a dewback...

Whoa calm down there Satan, unless you're group is loaded for rancor they're gonaa have a bad time, in fact, even if they are they still might have a bad time. Saarlaccs are pure nightmare fuel even in the larval stage and their only natural predators are Krayt dragons

I'd like these stats as well.

For particularly unruly player groups....
