Step 1:
The backside of the paper is completely white. Prefold over these 4 lines.

Step 6:
Hold the piece between two fingers, see large arrows. Then, press this piece flat from above with your other hand, see small arrow.

Step 5:
Pull the piece indicated by the arrow upwards by making a valley-fold over the green line.

Step 2:
Make a valley-fold over these 4 lines.

Step 4:
First, make a valley-fold over the 2 lines at the bottom-right. Then, make a mountain-fold over the 2 lines in the middle. And make a valley-fold over the 2 lines at the top-left.

Step 3:
Turn the model.

Step 10:
Press the edges indicated by the arrows flat from above.

Step 8:
Unfold the folds of step 7.

Step 9:
Pull the edge indicated by the arrow downwards by making a valley-fold over the green line.

Step 7:
Make a valley-fold over these 2 lines.

Step 16:
Repeat steps 13 to 15 on the other 3 same places of the model.

Step 15:
Push the 2 ends towards each other again, see arrows.

Step 12:
Repeat steps 6 to 11 on the other 3 loose pieces.

Step 11:
Fold the triangular piece below the green line upwards by making a valley-fold over this line.

Step 14:
Fold the triangular piece above the green line to the inside of the model by making a mountain-fold over this line.

Step 13:
Pull the 2 ends at the bottom of the arrows outwards, in the direction of these arrows.

Step 21:
Repeat steps 17 to 20 on the other 3 same places  of the model.

Step 19:
Make a valley-fold over these (prefolded) lines.

Step 20:
Now you've made an extra end. Fold this end upwards by making a valley-fold over the green line.

Step 18:
Pull the upper layer of paper loose from the rest of the model. Start pulling at the bottom of the edges, see arrows.

Step 17:
Push or pull the piece on the left and right of the green line upwards by making a valley-fold over this line.

Step 22:
Fold 2 flaps on the right of the green line to the left by making valley-folds over this line.

Step 28:
Press the model inwards from aside, see arrows. No new folding lines have to be made to do this.

Step 25:
Prefold over this line, fold the tip at the upper arrow to the corner indicated by the arrow below.

Step 26:
Open the model by pushing it outwards from the inside.

Step 24:
Repeat step 23 on the other side of the model.

Step 23:
Valley-fold over this line.

Step 29:
Now the model has the same shape as in step 25 again, but the top is folded downwards. Pull the end at the bottom of the arrow upwards.

Step 27:
Fold the center of the model downwards by making mountain-folds over these lines. These lines are prefolded in step 25.

Step 30:
Pull the layer of paper indicated by the 2 arrows outwards. Do the same on the other side of the end.

Step 31:
Fold over these 3 lines. Then press the model flat from aside, see arrows.

Step 32:
Pull the end indicated by the arrow upwards. Do the same on the other side of the model.

Step 33:
Pull the head a little to the right. Do this by making a valley-fold over the 2 lines at the right and a mountain-fold over the line at the left. Make the same folds on the other side of the head.

Step 35:
Mountain-fold over this line, make the same fold on the other side of the head.

Step 34:
Press the place indicated by the arrow flat between your fingers, to make sharper folding lines. Do the same on the other side of the head.

Step 36:
Make an inside reverse fold over these 3 lines  (=valley-fold over the 2 upper lines and mountain-fold over the line below)

Step 37:
Hold the nose between 2 fingers on the place indicated by the yellow dot. Then press the tip of the nose flat with your other hand, see arrow, against the fingers which are holding the nose.

Step 38:
Fold the right part of the brown piece to the right by making a valley-fold over the short green line. Do the same on the other side of the model.

Step 39:
Mountain-fold over this line, make the same fold on the other side of the model.

Step 40:
Mountain-fold over this line, make the same fold on the other side of the model.

Step 41:
Valley-fold to the left over the green line, see arrow. Do the same on the other side of the model.

Step 42:
Push the flap indicated by the arrow to the left by making a valley-fold over this line. Do the same on the other side of the model.

Step 43:
Pull the end at the bottom of the arrow upwards.

Step 44:
Pull the layer of paper indicated by the 2 arrows outwards. Do the same on the other side of the model.

Step 45:
Fold over these 3 lines. Then press the model flat from aside, see arrows.

Step 46:
Fold the pieces indicated by the arrows to the inside of the model again. All lines are prefolded. Do the same on the other side of the model.

Step 47:
Mountain-fold over this line.

Step 48:
Push the model flat from aside, see arrows.

Step 49:
Mountain-fold over this line, make the same fold on the other side of the model.

Step 50:
Mountain-fold over this line, make the same fold on the other front-leg.

Step 51:
Push the edge inwards by folding over these 3 lines (=valley-fold over the line in the middle and mountain-fold over the 2 outer lines)

Step 52:
Fold the brown part of the leg to the left by making a mountain-fold over the line on the right and a valley-fold over the shorter line on the left of the leg. Make these folds halfway the edge on the right, use arrows as guidance

Step 53:
Repeat step 51 and 52 on the other leg.

Step 54:
Push the leg inwards on the place indicated by the upper arrow. Then push the leg to the left on the place indicated by the arrow below. Do the same on the other front-leg.

Step 55:
Hold the model between two fingers on the place indicated by the yellow dot. Then press the ears downwards with your other hand.
