Twig array key errors I'm dumping this var but cant nail down this error:

{% set submissions = craft.tumblr.submissions %}
&lt;ul&gt;
    {% for key,submits in submissions %}
        // KEY GIVES ERROR 1
        &lt;li&gt;{{ dump(submits.key)  }}&lt;/li&gt;
        &lt;hr&gt;
        // BLOG_NAME GIVES ERROR 2
        &lt;li&gt;{{ dump(submits.blog_name)  }}&lt;/li&gt;
    {% endfor %}
&lt;/ul&gt;


Error 1:


  Key "key" for array with keys "blog_name, id, post_url, slug, type, date, timestamp, state, format, reblog_key, short_url, summary, recommended_source, recommended_color, followed, is_anonymous, anonymous_name, anonymous_email, is_submission, liked, note_count, title, url, link_author, excerpt, publisher, can_send_in_message, can_reply" does not exist


Error 2:


  Method "blog_name" for object "Twig_Markup" does not exist


Thoughts?

EDIT: Adding scheme for craft.tumblr.submissions:

  [1]=&gt;
  array(28) {
    ["blog_name"]=&gt;
    array(1) {

I'm not sure what submissions is, but submits inside your loop is an array so you can access its values using submits['blog_name'].
