Police in Palmview detained the driver after finding black tar heroin, cocaine, marijuana and several Ecstasy pills. Police say the Ecstasy was in brightly colored pills made to look like cartoon characters Homer Simpson, the Smurfs and even Obama.
Police spokesman Lenny Sanchez said the drugs look like a "vitamin for kids."
The 22-year-old driver in Monday's traffic stop is expected to face felony drug possession counts.
Palmview is near the border with Mexico.
