Need helping IDing a cel

I posted this on beta, but figured it wouldn't hurt to post this in both places. I just won a DBZ auction and can't place the cel. Any ideas?

Is it from an episode or movie? What episode?

I think this is from when goten and trunks are flying to see babidi and buu, and notice videl. I'll check later its a beautiful cel!

Ah, I found it! It is when they are fighting mr popo on the lookout!

You rock!
