Sesame Street Radio Control Construction Set
Give Elmo’s remote-controlled truck a delivery job: understand its forward and reverse controls, blue track and construction stops.

The play at a glance
A short journey through a busy worksite
The Sesame Street Radio Control Construction Set puts Elmo’s truck on a route with a bridge and construction scenery. The controller moves the truck; the places along the route give players reasons to pause.
The matching Fisher-Price model is 93778. A simple delivery story makes its movement purposeful without assuming that every piece of scenery is a separately controlled machine.
Know what the controller does
The 93778 guide shows a hood button that wakes the truck. The remote has forward and reverse arrows plus a separate horn button. It does not show a steering wheel or independent controls for each work station.
The blue route therefore matters. The assembly sheet matches lettered track ends and places accessories after the route is complete. Use its drawing on a hard, flat surface instead of guessing connections from the small photograph.
Mattel’s description names a swiveling bridge, Oscar’s wrecking ball and Ernie’s jackhammer. Those features belong to the setting; the documentation does not establish a fleet of individually motorized construction vehicles.
Try deliver, unload and return
For this original activity, name one loading place and one destination on the assembled layout. Use the set’s intended cargo if available, or simply describe an imaginary load. No extra objects are needed.
- Say who needs the delivery and why: a pretend path needs material, or a work station is waiting for supplies.
- Load at the starting place, then move the truck toward the destination.
- Pause the movement and describe the unloading. Let the customer say what happens next.
- Return for another job, or park the truck and finish the story.
Keep the first trip short enough to remember. A complete journey can be more satisfying than trying every feature at once. The child can choose the destination even when an adult helps manage the controller.
Make a stop part of the story
A bridge can be a meeting point or a reason to wait. A construction area can need a delivery, a visitor or a quiet moment while the crew decides what to do. Players supply those meanings rather than expecting the electronics to recognize them.
With two people, let one operate the truck while the other speaks for the worksite. Swap roles after the return trip. For a quieter round, leave the truck parked and talk through the next job with the figures.
A change in direction need not be a mistake. It can become a return visit, a forgotten delivery or the end of a shift.
Check the matching set before play
Compare the truck, remote, lettered track and bridge supports with the 93778 sheet. An adult should check for damaged connections and secure battery covers. The guide’s truck button wakes it rather than acting as an ordinary on/off toggle; consult the sheet when an older truck appears inactive.
A familiar Sesame Street name does not establish that another remote or roadway will work with this one. Keep this model’s controls and layout separate from other character-themed RC sets, and do not treat the old ease-of-use claim as a guarantee for an individual child or secondhand toy.
The historical record
Original Toysit coverage
The original description and general RC-construction essay are preserved below. Their review-like statements about ease, young children and hours of absorption are historical wording, not results of a new Toysit test. The essay’s broader list of remote-controlled machinery does not describe this set’s inventory.
Sesame Street Radio Controlled Construction Set by Fisher-Price
Sesame Street fans are in for an exciting tour of Sesame Street. This radio-control construction set includes a dump truck, lots of blue plastic track, a functioning bridge, work stations including a jackhammer and wrecking ball, a control unit, and figures of Elmo, Ernie, and Oscar the Grouch. Assembling the unit is easy: just match up the letters on the ends of the track pieces and snap in place. Radio-control cars are often extremely complicated to maneuver, but this unit's simple forward and back switches posed no problem for children as young as 2. This is a fun radio-control construction set that will have Sesame Street fans absorbed for hours.
An R/C (Remote Control) construction set offers a thrilling blend of hands-on building and high-tech control, capturing the imaginations of children and adults alike. These sets usually feature a range of construction vehicles like bulldozers, cranes, and excavators, all controlled via a remote. The joy comes not just from steering the vehicles around a makeshift construction site, but also from the functional aspects of these miniaturized machines—lifting, hauling, and digging just like the real thing. The R/C element adds an exciting layer of interactivity and realism, allowing for dynamic play scenarios that can change in an instant. This can be particularly educational for children, helping them understand basic engineering concepts, spatial awareness, and cause-and-effect relationships, all while offering hours of endless fun.

Reviewed October 16, 2026 using Mattel’s 93778 record and both scanned pages of its US instruction sheet. The track-letter layout, truck start button, remote and accessory drawings were visually reviewed. This set is distinct from Elmo’s Radio Control Roadway 39237. The delivery activity is an original suggestion; no physical set, radio range or scenery mechanism was tested.
