(A) shark(s) swallow(s) people; it pulls people into the water.
Although the meaning conveyed here is 'pull into' rather than 'push into' c.q. 'pull out of', this example shows the possibility of a serial verb construction involving transitive 'pull' and 'go', plus preposition. Here na ini, which is neutral with regard to 'motion' vs. 'at-rest', marks the goal. For Feature 82 "Transitive Motion Verbs 'Push'", cf. Example 208; for Feature 83 "Transitive motion verbs 'pull'", cf. Examples 204 and 207.
