Token copies of rosie cotton of south lane should not trigger their second ability from their own creation
Rosie's second ability triggers whenever you create a token. If you create a token copy of Rosie, for example with crooking counterpart, the copy triggers it's second ability, indicating that it sees it's own creation event, but it only gets onto the battlefield as a result of the creation.

ETB trigger events are checked AFTER the event happened, so a token Rosie does see itself being created.
603.6a Enters-the-battlefield abilities trigger when a permanent enters the battlefield. These are
written, “When [this object] enters the battlefield, . . . “ or “Whenever a [type] enters the
battlefield, . . .” Each time an event puts one or more permanents onto the battlefield, all
permanents on the battlefield (INCLUDING THE NEWCOMERS) are checked for any enters-the-
battlefield triggers that match the event.
