How sonic and tails meet

Well on SonicX, Tails' invention was destroyed by bullies in a forest. Later he tried to follow Sonic only to find his plane and began to `improve it`. Sonic came back while he was painting it and asked "What you up to?" they had a neutral conversation and their relationship blossomed from there, it was also when Sonic called him "Tails" instead of "Miles Prower".
