Following verbs take the infinitive without zu:

Example: Diese Spinne kann mir nichts tun. This spider can't hurt me.

Sometimes, in requests with müssen and sollen, you leave out the subject and the modal verb, so that only the infinitive remains.
Example: Du darfst dich nicht bewegen, sonst kommt die Spinne näher. → Beweg dich nicht! You must not move or the spider will come closer. → Don't move.
