Which word correctly indicates multiple entities?

For example, the sentence "Im Theater sehen sie einige seltsame Kreaturen auf der Bühne."

'Kreaturen' is the correct plural form of the noun 'Kreatur', which means 'creature' in English. In the context of the sentence, the plural is needed to refer to multiple strange entities on the stage. The other options are incorrect; 'Kreatur' is singular and doesn't match the context of indicating multiple entities. 'Kreatüre' and 'Kreature' are simply not correct forms of the noun in German.
