The Brazil international was greeted by dozens of children as he took the field for his last match at the Vila Belmiro stadium before he completes his move to Spanish side Real Madrid.
His team-mates lifted him into the air as he celebrated his first goal while he kneeled and kissed the pitch after converting the second.
Santos raced to a 4-0 lead in half hour with Robinho's two penalties and goals by Elton who fired home a rebound after Ricardinho's shot hit the crossbar and former Barcelona and Olympiakos midfielder Giovanni.
But the Brazilian champions suffered a fright as struggling Figueirense replied with three goals in 13 minutes after halftime from Cleber Michel Bastos and Edmundo.
Cleber also hit the crossbar with a header in the 77th minute.
'I'm very happy' said Robinho who has one more game to play for Santos away to Paysandu on Wednesday.
'I wanted to bid farewell to the Vila with a win.'
Santos moved up to fourth in the table with 36 points from 21 games.
Corinthians who have 39 points stayed top as the competition reached its halfway stage after a late equaliser gave them a 1-1 home draw against second-placed Goias who are two points behind.
Striker Souza's close-range effort gave Goias a tenth-minute lead which they held under Marcelo Mattos equalised in the 85th minute.
Atletico Paranaense avenged their Libertadores Cup final defeat to Sao Paulo by beating the same opponents 4-2 in a stormy match played in their Arena da Baixada stadium in Curitiba.
Paranaense were not able to use the stadium for their home leg of the Libertadores final because its 24000 capacity was too small under competition rules.
The match got off to a rough start as Sao Paulo defender Alex was sent off after 10 minutes for a vicious sliding tackle on Fabricio who was stretchered off and is expected to be out for eight weeks with a knee injury.
As the two team benches and the players exchanged insults Sao Paulo went ahead when former Paris St Germain striker Christian scored on his debut.
Alan Bahia levelled three minutes before the break then Ferreira scored two goals in a six-minute spell after halftime the first a penalty to put Paranaense in control.
Jancarlos added the fourth in style with a superb individual goal after he slipped the ball between the legs of Edcarlos though he was sent off for removing his shirt in the celebration.
Amoroso pulled one back with an injury-time penalty.
The defeat sent Sao Paulo back into the relegation zone leaving them 19th in the 22-team table with 21 points.
'They came for a war' Paranaense coach Antonio Lopes said. 'The foul on Fabricio was a violent act.'
