Axel & Pixel

For this achievement you need at the end of the game a score of +42k.
to get +42k points at the end of the game you need the 20 bones, 8 sketches and 8 tubes of paint. Don't use hints (you lose 250 points for each hint) and round a click score from 800+ (the rest moves you have after any chapter)

but don't give up or start a new run when you didn't get the achievement while you use hints ore you didn't get enough points.
First start the three mini-games, balloon, car and boat. and get the three achievements



You need in each of the 3 mini-games +10k score to get the achievement and this points stack on your final score (but that didn't shown in your stats at the end ;))
Start, after the three mini-games the last chapter again
wait until Alex finish his paint and viola you have the 50 gs for the achievement :D

i used 2 hints (lost 500 points) and finish the game round 41800 -.- after beat the 3 mini-games the achievement pop up
hope that helps

I was messing around with my Capture Card and just so happened to record myself collecting all Bones, Paintings and Color Tubes during my play through, so I thought I'd upload them.

You will unlock Dog's Dinner after you collect the final bone, however, the other collectible related achievements are unlocked AFTER the Outro, including this one.

Apologies for the lack of HD...I didn't know it was set to 480p until after I had recorded it, but if they help even one person it was worth uploading.
