Answers.Body: <p>I just found the answers to 75% of my question! I was scrolling BrickLink for &quot;duplo tube&quot; since I have several of those pieces, then found the blue dome with eyes: it's &quot;<a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=40711pb01&amp;idColor=7" rel="noreferrer">Duplo Ball Tube Cover Ring Hinged Top with Eyes</a>&quot;. It only appears in <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?S=3266-1" rel="noreferrer">one set</a>, and attaches to <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=40710&amp;idColor=3" rel="noreferrer">another piece</a> which I don't have, which then connects to the tubes, so that's why I didn't know it related to the tube pieces.</p>
  <p>In this set's inventory, I then found two more of my pieces: the green hopper, which is &quot;<a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=31025&amp;idColor=6" rel="noreferrer">Duplo Loading Chute with 2 x 4 Base Bricks</a>&quot;, and the red/blue inverted domes, which are &quot;<a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=31367&amp;idColor=7" rel="noreferrer">Duplo Egg Base</a>&quot;. So I was right about the bases relating to the tubes, but they don't actually connect to them, they just sit there.</p>
  <p>I haven't identified the yellow axle brick though!</p>

Body: <p>I don't collect Duplo so I'm not familiar with a lot of the pieces they have. Here are the four that stump me:

  <a href="https://i.sstatic.net/csdyU.jpg" rel="noreferrer"><img src="https://i.sstatic.net/csdyU.jpg" alt="duplo brick" /></a></p>
  <ul>
  <li><p>4x10x3-ish freight hopper: I searched &quot;duplo hopper&quot; in BrickLink but only got <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=31303&amp;name=Duplo,%20Train%20Freight%20Hopper%20Compartment&amp;category=%5BDUPLO,%20Train%5D" rel="noreferrer">this</a></p>
  </li>
  <li><p>2x2 brick with axle(?). The axles are hollow up to the edge of the brick</p>
  </li>
  <li><p>2x2 blue dome brick with eyes and a clip. The studs are hollow</p>
  </li>
  <li><p>5x5-ish dome bricks with a 2x2 centre. They have two tiny holes in the bottom, and a groove at the top. Initially I thought they belonged with the <a href="https://www.bricklink.com/v2/catalog/catalogitem.page?P=31195&amp;name=Duplo%20Ball%20Tube%2045%20degrees&amp;category=%5BDUPLO%5D" rel="noreferrer">tube</a> system pieces because I have several of those, but the circle size is too big for that.</p>
  </li>
  </ul>
  <p>None have dates on them.</p>
  <p>Thanks!</p>

  I just found the answers to 75% of my question! I was scrolling BrickLink for "duplo tube" since I have several of those pieces, then found the blue dome with eyes: it's "[Duplo Ball Tube Cover Ring Hinged Top with Eyes](https://www.bricklink.com/v2/catalog/catalogitem.page?P=40711pb01&idColor=7)". It only appears in [one set](https://www.bricklink.com/v2/catalog/catalogitem.page?S=3266-1), and attaches to [another piece](https://www.bricklink.com/v2/catalog/catalogitem.page?P=40710&idColor=3) which I don't have, which then connects to the tubes, so that's why I didn't know it related to the tube pieces.
  
  In this set's inventory, I then found two more of my pieces: the green hopper, which is "[Duplo Loading Chute with 2 x 4 Base Bricks](https://www.bricklink.com/v2/catalog/catalogitem.page?P=31025&idColor=6)", and the red/blue inverted domes, which are "[Duplo Egg Base](https://www.bricklink.com/v2/catalog/catalogitem.page?P=31367&idColor=7)". So I was right about the bases relating to the tubes, but they don't actually connect to them, they just sit there.
  
  I haven't identified the yellow axle brick though!
